1. What are the various available cloud service models?

IAAS - IaaS rents hardware/infrastructure as a service to enterprises - for example, memory, computing, servers. Organisations deploy their applications on Cloud Providers infrastructure.

SAAS - SaaS offers users software as a service that resides on the cloud. Software and applications are used on a subscription basis. Cloud providers are responsible for the maintenance and upgrade of the software. Communication with Applications happens over API calls advised by the Cloud provider—for example, Google Drive.

PAAS - PaaS provides enterprises with a platform where they could deploy their code and applications. PaaS packages the platform for development and testing along with data, storage, and computing capability.

2. What are the component layers found in Cloud architecture? 

Cloud Controller (CLC) - CLC sits at the topmost layer and controls virtual resources like servers, networks, and storage.

Walrus - It acts as a storage controller for users and deals with virtual machine images and user data.

Cluster Controller - It controls the execution of all the virtual machines stored on the nodes. 

Storage Controller - Storage controller handles storage in block form that is dynamically attached to virtual machines

The Node Controller - It controls the functionality of the hypervisor that controls VM activities. The hypervisor is a hardware-supported emulation technique that allows multiple OS to run on the same host OS. also called virtual machine manager.

3. What are some popular use cases for cloud computing?

  • Cloud storage - Storage over the internet through a web interface turned out to be a boon. With the advent of cloud storage, customers could only pay for the storage they used. From Google Drive to more privately operated proprietary applications, cloud storage is everywhere. 
  • Big data analytics - Big data and Cloud technologies go hand in hand and essentially make systems faster, scalable, failsafe, high-performance, and cheaper.
  • Test and Development - Cloud provides ready-to-use, customised, and fully set up resources. It offers the infrastructure for the testing and development of applications and services without the downside of installing and maintaining the on-premise resources, servers, and environment. 
  • Disaster Recovery - Data recovery is cheaper and faster in Cloud Computing technology. Since a cloud ideally stores the data on many different servers in different locations, the probability of complete data loss reduces. 
  • Data Backup - Data backup is more effortless and comes with security and availability of resources. Older backup strategies had loopholes with the physical disc getting corrupted or running out of stock.

4. What is On-Demand functionality?

Cloud consists of a shared pool of resources and systems. The resources lent to the customer can be changed on customers’ demand. On-Demand design saves customer’s overhead and provides easy scalability.

5. What are the platforms that use Cloud Computing?

Map-reduce - Map-reduce enables users to use resizable Hadoop clusters within Amazon infrastructure. Amazon’s counterpart of this is called Amazon EMR ( Elastic Map-Reduce)

Hadoop - Hadoop allows clustering of hardware to analyse large sets of data in parallel. 

Apache Spark - Apache Spark is an open-source analytics engine that computes and processes large datasets. The processing happens in memory for the sake of high performance. It provides parallel processing and fault tolerance by cluster management. Apache Spark forms the complete big data solution along with HDFS, Yarn, Map-Reduce.

6. What are the different modes of deployment available on the Cloud?

There are four modes, namely private cloud, public cloud, and hybrid cloud, community cloud.

Public - A public cloud is free to use for anyone. E.g. AWS Cloud Connect. 

Private - Private cloud is the collection of resources that private organisations use for their own needs.

Community cloud - It allows multiple organisations in a group to access services and systems to share information and computing.

Hybrid cloud - Hybrid cloud is a mix of private and public clouds that can switch from one to another, depending on the conditions and requirements.

7. What is the difference between scalability and elasticity?

Scalability is the characteristic that allows resources to be increased/decreased, corresponding to the customer’s workload. Say, for example, the traffic starts to increase on the customer side, and the current resource allocation is falling short. We would need to scale up our product and get more resources from the cloud provider on-demand in such a case.

Elasticity refers to commissioning and decommissioning large amounts of resources dynamically depending on where the traffic is high or low. Elasticity comes in handy when in a shared cloud, two customers are competing for resources. One customer can forfeit some unused resources to the other customer who is falling short and requires resources.

8. How is Cloud computing different from mobile computing?

Mobile Computing, as the name suggests, is related to Mobile devices and tablets. It is responsible for accessing the internet and performing searches and application tasks for mobile systems. Compared to Cloud computing, Mobile computing is more customer-centric. In contrast, customer-oriented cloud computing aims at the enterprise level and deals with organisations and their services.

9. Why use Cloud Computing?

Cloud computing is the process/idea of renting/delegating computing resources from dedicated servers and cloud providers over the internet. Services can be storage, web servers, infrastructure, etc. With the use of cloud computing technologies, organisations can ensure quality control and make their products scalable, modular, and collaborative. The term Cloud-native defines a product that leverages cloud technology.  

10. What is cloud-native?

Cloud-Native are technologies and services built to leverage cloud architecture. 

11. What are some examples of popularly used Cloud Computing services?

Windows Azure, Amazon Web services, and iCloud are the very popular ones. Oracle Cloud and IBM cloud are present as market competitors as well.

12. What is Edge computing?

Edge Computing is done at a centralised place with resources present locally. A direct benefit is low latency and less dependency on outside resources.

13. What do you know about the Multi-cloud strategy?

The strategy dictates to not rely completely on a single cloud service provider and distribute the traffic among multiple cloud service providers. Different functionalities can be leveraged from different cloud providers, thus reducing work from one particular provider. This helps in increasing independence and lowers the risk of failure in the case the provider faults or there occurs a traffic overload. Multi-cloud comes in use as a design to govern from a singular access point ( portal )over the multiple cloud architecture. It can be as simple as a portal to overlook all the clouds and their functionality.

14. What are the basic types of Data Centers?  

Containerized or High-Density data Centers - These are faster but take more power and generate heating issues. Also, it is cheaper for the customer.

Low-Density Data Centre - Servers are placed some distance apart in a low-density data centre. That is why the name low-density. Due to the more spaces between two servers, heating is never an issue. 

15. How is security ensured in Clouds? 

  • Identity management
  • access control
  • authentication
  • Authorisation

16. What is Elastic Utility Computing Architecture - EUCALYPTUS?

It is an open-source software infrastructure in cloud computing to create private, public, and hybrid clouds. And link programs to the systems and build data centres.

17. What is a cloud VPN?

Cloud VPN helps companies transition their VPN services to the cloud. There are two types of VPN services that are available - Remote Access and Site to Site connection.

A VPN appliance is installed on-site in the company network in a Site-to-Site connection. This appliance connects to a virtual VPN endpoint in the cloud. The VPN results in a  tunnel between the cloud and the enterprise. This connection doesn’t need the public IP address and acts similar to a physical connection. 

Remote Access enables users to connect to machines located elsewhere globally. For example - VPNaaS. 

In the connection logic, users install VPN software on their machines and connect to cloud VPN. The cloud VPN forwards the connection to the concerned SaaS application.

Cloud Computing Interview Questions for Experienced

1. What is Virtualization in Cloud Computing?

Virtualisation provides an abstraction between the back end and user programs. It enables creating an environment where multiple software can use the same hardware. Virtualisation also manages the service level policies. Following are a few types of virtualisation seen in Cloud Computing.

Server Virtualization partitions a server into multiple serves so it can distribute incoming traffic among them. The use case is load balancing.

Hardware Virtualization is where Virtual Machine Manage installs on the hardware. It provides easy access and monitors of resources like memory, processors, etc.

Storage Virtualisation takes multiple Network storage devices and clubs them into one single group, providing abstraction. The group is easier to maintain when compared to numerous devices inside it.

Operating System Virtualisation is when multiple OSs run on the same hardware. It is possible by installing the VMM onto the host OS instead of the hardware.

Desktop Virtualisation allows remote access to workstations across global data centres, managed over the internet.

Application Virtualisation ensures applications that run on one operating system can run on other operating systems as well. It creates an abstraction between the OS and the application.

2. How is Data protection in S3 achieved?

Data can be encrypted in S3 using SSE-S3, SSE-C, SSE-KMS.

SSE-S3 provides the solution S3 oversees Key management and protection using multiple layers of security. 

SSE-C lets S3 perform encryption and decryption of data and control the key used for encryption. Key management and storage are implementation-dependent and not provided by AWS.

SSE-KMS uses the Amazon Key Management service to store the keys used in encryption. KMS also provides an additional layer of security by keeping master keys. Special permission is needed to be able to use the master key.

3. What are the differences between ELB, NLB, and ALB?

Application Load Balancer (ALB) - ALB allows routing based on port numbers. It can also route requests to Lambda, and it can direct requests to many ports on the target. Application Load Balancer supports only layer 7 - HTTP/2 and Web Sockets. It can return primary responses on its own so the server can be set free of replying to redundant requests. ALB find use in Microservices and application

Network Load Balancer (NLB) -  Network Load Balancer supports Layer 4 that is TCP and UDP. It is faster and high-performance since it is lower in the OSI model. It uses static IPs and can also be assigned elastic IPs. An example would be real-time data streaming or video streaming.

Classic Load Balancer (CLB) or Elastic Load Balancer (ELB version1) - ELB is the oldest Load balancer and the only one which offers application-specific sticky session cookies. It works both on Layer 7 and Layer 4. ELB also supports EC2-Classic. 

4. Explain the types of EC2 instances? 

Memory-Optimized Instances - They provide fast performance for applications that process Bigdata in memory. Memory Optimised instance includes support for enhanced networking, up to 25gbps of Network Bandwidth. They come packaged with EBS installed and optimised.

Use cases are in-memory caches and open-source databases. 

Compute Optimised Instances - Compute Optimised instances provide high-performance computing resources and fast batch-processing. They are used ideally for media transcoding, gaming servers, ad-server engines. Compute Optimised Instances use the AWS Nitro system, which combines dedicated hardware and lightweight hypervisors. Just like Memory-optimized, Compute Optimised Instances come with optimised EBS as well.

Accelerated Computing Instances - These Instances use co-processors and hardware accelerators to improve upon the performance. They get used in graphics processing, floating-point calculations, data pattern matching. Accelerated Computing Instances use extra hardware power to combat software limitations and latency. These also support the Elastic Fabric Adapter (EFA)

Storage Optimised Instances - Storage Optimised instances are ideal for workloads that need high sequential read and write. These instances use their local storage to store data.

Storage optimised instances provide low latency and high-speed random I/O operations. They get used in NoSQL databases like Redis, MongoDB , data warehousing.

General Purpose instances provide a mixture of computing, memory, and networking resources. General Purpose Instance find their use in applications that consume multiple resources in equal proportions, for example, web servers, code repositories.

5. What is Cloudformation’s function? 

CloudFormation helps in creating and maintaining an AWS infrastructure and stacks. Stacks are a collection of AWS services. And CloudFormation enables users in creating stacks quickly with minor overhead. One could ideally configure the AWS infrastructure through a text or JSON file in Cloud Formation.

6. How does AWS provide defence from Distributed Denial of Service (DDoS) attacks?

Amazon AWS provides Shields for security against attacks. AWS Shields uses two tiers of security- Standard and Advanced . 

Standard AWS Shield, which comes by default with AWS, can be used as a first-measure security gate. It protects network and transport layers.

Subsequently, one can also subscribe to Shield Advanced for another layer of added security. The AWS Advanced Shield provides integration with AWS Web Application Firewall (WAF). AWS WAF provides custom rules to filter out traffic with threat signatures.

Web Application Firewall provides three main actions: allow all requests for a rule, block all requests, and count all requests for a new policy.

Advanced Shield also extends 24x7 support from AWS DDoS response team.

Aurora is the database engine that gives reliability and speed at par with industry-standard databases. It backs up data in AWS S3 in real-time without any performance impact. It backs up storage in a routine fashion without the hassle of Database administrators interfering.

RDS (Amazon Relational Database System) is the traditional relational database that provides scalability and cost-effective solutions for storing data. It supports six database engines, i.e. MySQL, Postgres, Amazon Aurora, MariaDB, Microsoft SQL Server, Oracle.

8. How can DDos attack be prevented and minimised?

  • Shield ( Standard and Advanced )
  • WAF ( web application firewall )
  • Route 53 ( DNS ) 
  • ELB ( Elastic Load Balancing)
  • VPC ( Virtual Private Cloud)
  • CloudFront 

9. What are the limitations of ELB?

  • ELB isn’t compatible with EKS containers running on Fargate.
  • It can route traffic on more than one port in an instance
  • ELB doesn’t support forwarding data to IP addresses. It can only forward it to the EKS/ECS container or EC2 instance.
  • It also doesn’t support web sockets.
  • In ELB, there is no concept of target groups in routing.

10. How are target groups used to provide an additional level of redirection in Load Balancing?

Target groups are another layer of abstraction and redirection created in load balancers. They are tagged into three types while creating target groups - instances (marked by instance ID), IP address, and Lambda functions. Dedicated listeners listen to the traffic coming in the load balancer and route traffic to the appropriate target group. The target group then routes the data to specific IPs, instances, and containers. The Target group checks the health of its targets and figures how to split the oncoming traffic.

1.   What are the key components of an AWS architecture?

Route 53, email service, identity management, and access management, simple storage device, elastic block stores, cloud watch

2.     How does AWS provide security for its customers?

Infrastructure security  

The Network firewall built into Amazon VPC lets you create a private network and control access to applications and services.

Data encryption 

AWS CloudSHM provides hardware-based cryptographic key storage, helping users in enforcing their compliance requirements. AWS services like AmazonEBS, AmazonS3, Amazon Lambda have built-in encryption features in them. These encryptions provide another layer of security.

Identity and access control 

Amazon Identity and Access Management let you enable permissions for each user account and offers various multi factors authentication that is hardware-based and software-based.

Monitoring and logging 

With AWS CloudTail, one can AWS deployments in the cloud by getting the history of API calls and commands executed.

Amazon CloudWatch provides scalable and flexible monitoring solutions for the cloud.

Amazon Guarduty is a solution that checks and scans for malicious activities in the system.

3.   What is Amazon Machine Image - AMI?

AMI is an image of the operating system, application server, and applications that will run on the cloud server. Running an image will create an instance on the cloud. AMI includes metadata of the root volume. It also has permission to decide on AWS instances that will be allowed to run it.

4. What is AWS lambda?

Lambda is a computing service that runs your code without requiring and managing servers. Each client request will instantiate a new lambda function. Lambda charges you for only the time when the code was running.

5.     How can AWS  vertically scale in AWS?

Vertical scaling is adding more RAM and processor power to the existing machine. AWS provides instances up to 488 GB ram or 128 virtual cores. To initiate vertical scaling, one first needs to decouple the tiers in our application. These tiers will be distributed and handled by web servers. Finally, we can run the newer instance and make appropriate changes reflecting the vertical scaling.

AWS Ops Automator automatically adjusts capacity to maintain steady, predictable performance at the lowest possible cost. The solution can resize the instances by restarting your existing instance with a new size. Or, the solution can resize your instances by replacing the current instance with a new, resize instance.

6.   What are important features of Amazon S3

  • S3 Storage class provides enterprise-wide insights and best practices for running storage buckets more efficiently and safely. 
  • S3 batch operations make jobs run in parallel by running them in batches. Batching together jobs helps to increase efficiency.
  • S3 Intelligence tier is the feature where highly accessed data objects move to low-cost buckets. 
  • Identity and access management (IVM) manages access to different parts of Amazon S3.
  • Access Control List allows access to certain traffic to every bucket or object.
  • Versioning is to store multiple versions of the same file on the storage.
  • S3 offers Multi-Factor Authentication Delete so that the data doesn’t get deleted by human error or accidents.

7. DB used in AWS 

MariaDB, Postgres, MongoDB, Oracle, MySQL are some common databases used in AWS.

8. Different types of load balancers in AWS

  • Classic Load Balancer - Classic load Balancer is the only one among the three that supports EC2 classic instances.
  • Network Load Balancer - used when needing high performance and static IPS 
  • Application load balancer - used when you need flexible application management and TLS termination.

9.   What is elastic IP

EC2 instances use Elastic IP for communication over the internet or in a private network. You first allocate to your AWS account and then can map it to instances. It can avoid system failure when a resource fails. Fail-safe is ensured by remapping the faulted instance’s IP to a new instance.

10.How is elastic IP allocated?

Elastic IPs are allocated by going to the EC2 console  

https://console.aws.amazon.com/ec2/

Go to Network and security > Elastic IP > allocate elastic IP > Navigation

11. What is Elastic Load Balancing ( ELB )?

 ELB distributes oncoming traffic among multiple EC2 instances and helps in fault tolerance.

a.        Load balancer – involves distributing incoming requests among EC2 instances registered with it.

b.      SSL termination – ELB offers SSL encryption and decryption build into the EC2 instances attached to ELB

c.       Control service – This automatically scales the system by adding more load balancers to the EC2 instances.  

12. What is Amazon Route53?

Route53 is a highly scalable and available domain name system (DNS) provided under Amazon AWS. These are the three prime functions

a.       Register domain names

b.      Route internet traffic to resources

c.       Send health checks to resources and devices.

13. What is the EC2 (Elastic Compute Cloud) instance?

Elastic Cloud Compute instance developers manage to compute on-demand in the AWS cloud. It gives control over web scaling and computing resources.

EC2 instances are resizable upon requirement. Depending on the data traffic the organisation faces, EC2 instances shrink or expand in size. One can access EC2 instances over many geographical locations called availability zones.

14. What are some benefits of CloudFront?

Cloud front is a Content delivery network developed by amazon that delivers data with high speed and low latency globally through its worldwide web of data centres. 

It caches content in edge locations and local regions, resulting in quicker data availability. If the data isn’t present at the edge location, it retrieves it from the specified path, like an S3 bucket.

Data transfer happens over HTTP and HTTPS

Copies of the files are ideally held across multiple edge locations globally. The redundancy increases reliability and availability. 

By default, copies of objects ( or files )remain cached at the edge locations 24 hours before expiring. 

15. What is the Elastic BeanStalk?

Elastic BeanStalk acts as a console for deploying Amazon services by reducing the complexity of the environment. It takes care of the setup of resources. One simply has to upload the app, and Elastic Beanstalk takes care of the setup and managing resources/services. Services like load balancing, scaling, health monitoring, and on-demand provisioning get handled by EBS.

Elastic Beanstalk provides Amazon AWS resources like EC2 and builds the supported platform for the project to run. It supports PHP, GO, Java, Node, .NET, Python, and Ruby. The Elastic BeanStalk console can manage most deployment tasks through the Elastic Beanstalk Console, like changing the size of EC2 instances and monitoring resources.

16. What is S3 in AWS?

S3 or Simple Storage Service provides key-based object storage through a web service interface. Key can be any string that is assigned when an object gets created in the storage. It offers read-write consistency. Once the object is updated, the subsequent request receives the updated version of the object.

17. How is AWS IVM helpful in threat detection?

Firewall with policies.

18. How are S3 and EBS different from each other?

Simple Storage Service and Elastic Block storage are the two kinds of storage options provided by AWS for data storage. The differences arise mainly from their compatibility with other AWS services.

  • EBS is used only with EC2 instances. S3 comes with no such limitation, popularising its use outside EC2.  
  • EBS comes as a mountable volume while S3 provides read/write through software.
  • S3 suffers from write delays while EBS soars. 
  • EBS can bind with only one EC2 instance. On the other hand, multiple instances of EC2 can bind with S3.
  • S3 used versioning and cross-region replication for data backup. At the same time, EBS relies on snapshots and automated backups. 
  • S3 resources can be provisioned or decommissioned in runtime, supporting scalability. EBS needs manual intervention to increase or decrease resources.
  • Generally, S3 can store larger amounts of data when compared to EBS.
  • S3 replicates data across multiple availability zones while EBS stores replicas in only one availability zone. 
  • Amazon S3 stores large data sets, but EBS is the block storage unit for the EC2 instances, like hard drives for PCs.
  • Use cases for EBS are Software development and testing, NoSQL databases, organization-wide application.
  • USe cases for S3 back and restore, Big Data analytics, disaster recovery.

The role that a company is hiring for will mostly dictate the questions in the interview. It will also depend on the experience level of the interviewee. Freshers get asked more conceptual and use-case dependent questions. At the same time, experienced Cloud Engineers should expect more architecture and design-related questions. 

Prepare for one particular Cloud technology extensively. 

It is best to choose a technology one has experienced already and master it. All Cloud Computing technologies share the basic architecture and design. So, knowing one technology ( say, Microsoft Azure ) in and out will help to relate to other technologies better. It is advisable to learn the architecture of one specific technology. Some hands-on is also appreciated since it can set one apart from others candidates.

A fresher might start with Amazon Web Services since it has the most number of studying resources over the internet.

Familiarise with Cloud Computing Terminology

The interviewee must be able to converse easily in Cloud Computing jargon. To have the knowledge and to be able to convey it properly are separate fortes altogether. It isn’t mandatory to know all the keywords and nit-picks on industry vocabulary, but it helps to know the basic terminologies. 

Speak your thoughts 

A common Interview advice, but one that gets overlooked quite often, is to Speak your Thoughts. Doing so ensures that the interviewer is in sync with the interviewee’s thought process. And many times, interviewers aren’t strictly after the right answer, but the problem-solving mindset. 

Say, for example, AWS CloudFormation and AWS Elastic Beanstalk both provide deployment and monitoring ease for apps using AWS. They offer the same services with different degrees of control and usability. The interviewee can use one service to explain the same question ( or concept ) when he doesn’t know the other technology. This would be possible if the interviewee were transparent with his thought process and knowledge level.

Know the differences between the Cloud Platforms 

It can be advantageous to know the difference between the available Cloud Computing Technologies. Knowing the difference will help in understanding how different architectures tackle the same problem. In summary, learn the difference between AWS, GCP and Microsoft Azure. For Example, Kubernetes automates deployment, testing, scaling and operation of application containers across clusters of hosts. Google first deployed it to automate the deployment process by running containers in clusters. Soon, other technologies picked up and came out with their proprietary Kubernetes version.

The next step to go from here would be to study the individual Cloud Computing technologies - Amazon Web Services, Microsoft Azure, Google Cloud Platform. Amazon Web Service stands as the most popular among them and an industry favourite. These  AWS Interview Questions will help you get a jump start. Another good topic to start would be Big Data since Cloud Computing, and Big Data are generally coupled with applications.

Top 25 Cloud Computing Interview Questions and Answers

Prepare for your next Cloud Computing interview with our comprehensive list of commonly asked questions and detailed answers, designed to help you land your dream job.

cloud computing assignment questions and answers

Cloud computing, a revolutionary paradigm shift in the world of information technology, has become an integral part of modern business infrastructure. This innovative model for enabling ubiquitous and on-demand network access to a shared pool of configurable computing resources has transformed how businesses operate today.

From data storage and management to processing power and software applications, cloud computing provides organizations with scalable IT capabilities that are flexible, cost-effective, and accessible from anywhere around the globe. Its widespread adoption across diverse industries such as healthcare, finance, retail, and more underlines its universal appeal.

In this article, we delve into a variety of interview questions about cloud computing, offering comprehensive answers designed to enhance your understanding of this transformative technology. These questions cover core topics including types of cloud services (IaaS, PaaS, SaaS), virtualization, security, architecture, and more. Whether you’re an aspiring cloud professional or an experienced practitioner, these questions will serve as an invaluable resource to sharpen your knowledge and skills.

1. Can you discuss the difference between vertical and horizontal scaling in cloud computing?

Vertical scaling, also known as “scaling up”, involves enhancing the capacity of a single server by adding more resources such as CPU or RAM. This method is simple to implement but has limitations due to hardware constraints.

Horizontal scaling, or “scaling out”, on the other hand, involves adding more servers to distribute the load evenly. It offers greater flexibility and reliability since it doesn’t rely on a single server’s capacity. However, it requires sophisticated load balancing and data distribution strategies.

While vertical scaling can lead to better performance for individual tasks, horizontal scaling supports larger, distributed systems and helps in handling increased traffic or load effectively. The choice between these two depends on the specific needs and architecture of the system being scaled.

2. How do you approach securing cloud-based infrastructure?

Cloud security involves a multi-faceted approach. Firstly, data encryption is crucial for both stored and transmitted data to prevent unauthorized access. Secondly, identity and access management (IAM) should be implemented to control who can access the cloud resources. Regular audits of IAM policies ensure they remain effective.

Thirdly, secure APIs are essential as they provide interfaces between cloud services and users or other services. They must be designed with robust authentication and authorization mechanisms. Fourthly, intrusion detection systems (IDS) and firewalls should be deployed to monitor and block suspicious activities.

Fifthly, disaster recovery plans need to be in place to restore operations quickly after an incident. This includes regular backups of data and applications. Lastly, compliance with relevant regulations such as GDPR or HIPAA is necessary to avoid legal issues.

3. How would you deal with a cloud service provider outage?

In the event of a cloud service provider outage, I would first verify the outage using independent monitoring tools. If confirmed, I’d communicate this to stakeholders and activate our disaster recovery plan. This could involve switching to a backup provider or reverting to on-premise systems if available. Meanwhile, I’d maintain communication with the affected provider for updates and estimated resolution times. Once services are restored, I’d conduct a post-mortem analysis to understand the cause and improve future responses.

4. Can you describe the differences between IaaS, PaaS, and SaaS?

IaaS, or Infrastructure as a Service, provides users with virtualized computing resources over the internet. It’s like renting physical infrastructure, but in a virtual environment. Users have control over their infrastructure but not the underlying cloud architecture.

PaaS, Platform as a Service, is a cloud service that provides developers with a framework they can use to build upon and create customized applications. The user controls software deployment and configuration settings, but not the underlying servers, storage, or network.

SaaS, Software as a Service, delivers applications over the internet on a subscription basis. In this model, the service provider hosts and maintains the software application and underlying infrastructure, and handles any maintenance, like software upgrades and security patching.

5. Describe a situation in which you had to migrate a traditional infrastructure over to cloud-based architecture.

In my previous role, we migrated our company’s traditional on-premise infrastructure to a cloud-based architecture. The primary reason was scalability and cost-effectiveness. We chose AWS due to its robustness and wide range of services.

The migration process began with an assessment phase where we identified the applications and data that needed to be moved. This included customer databases, internal tools, and web servers.

Next, in the planning stage, we designed the new architecture using EC2 for compute power, S3 for storage, and RDS for database management. We also planned for security measures like IAM roles and VPCs.

During the execution phase, we used AWS Migration Service to move data without downtime. Applications were reconfigured to work in the new environment.

Post-migration, we monitored performance and made necessary adjustments. Regular audits ensured compliance with industry standards.

This migration improved our system’s scalability, reduced costs, and increased operational efficiency.

6. What is “Sharding” and how is it used in cloud databases?

Sharding is a database partitioning technique used to distribute data across multiple servers, enhancing the performance of cloud databases. It involves splitting large databases into smaller parts called ‘shards’, each holding a portion of the total data. Shards are distributed across different server instances, reducing the load on any single server and improving query response times.

In cloud computing, sharding is crucial for scalability as it allows databases to accommodate more data by adding more servers. This horizontal scaling strategy ensures that as the database grows, its performance remains consistent.

However, implementing sharding requires careful planning. The distribution must ensure balanced loads across all servers to prevent some shards from becoming bottlenecks. Also, related data should be co-located in the same shard to minimize cross-shard queries which can degrade performance.

7. Can you explain how to implement a multi-cloud strategy and its benefits?

A multi-cloud strategy involves using multiple cloud computing services from different providers. To implement it, first identify the business needs and match them with the right cloud service provider. This could be based on cost-effectiveness, performance, or data sovereignty requirements. Then, design your applications to be portable across these platforms by adopting a containerization approach like Docker or Kubernetes.

The benefits of this strategy include risk mitigation against single vendor dependency, improved disaster recovery capabilities, and increased flexibility. It allows businesses to leverage best-of-breed solutions for specific tasks, potentially leading to better performance and cost savings.

8. What is your approach to ensuring data integrity in a cloud environment?

Data integrity in a cloud environment can be ensured through various strategies. Implementing robust access control measures is crucial to prevent unauthorized data modification or deletion. This includes strong authentication protocols and role-based access controls. Regular backups are also essential, allowing for data recovery in case of accidental loss or corruption. Data encryption, both at rest and in transit, provides an additional layer of security against breaches. It’s important to use reliable cloud service providers that offer built-in redundancy and fault tolerance mechanisms. Regular audits should be conducted to monitor the effectiveness of these measures and identify potential vulnerabilities.

9. How would you troubleshoot a slow cloud network?

To troubleshoot a slow cloud network, I would first check the bandwidth usage. If it’s high, I’d identify which applications are consuming most of it and take necessary actions. Next, I’d verify if there is any latency issue with the Internet Service Provider (ISP). If so, contacting them for resolution would be my next step.

If these steps don’t resolve the issue, I’d then look into the server-side issues. Checking the performance metrics of the server like CPU utilization, memory usage, disk I/O can help identify bottlenecks. If the server is under heavy load, optimizing the application or scaling up resources could be considered.

Lastly, I’d review the configuration settings of the cloud service. Incorrect configurations such as improper routing rules or firewall settings can also cause slowness.

10. How would you manage and monitor cloud resources to maintain optimal performance?

Cloud resource management and monitoring for optimal performance involves several key steps. First, it’s crucial to implement a robust cloud monitoring tool that provides real-time insights into the health of your resources. This includes tracking CPU usage, memory consumption, network latency, and disk I/O operations.

Secondly, setting up alerts based on predefined thresholds can help detect anomalies early and prevent potential issues from escalating. For instance, if CPU utilization exceeds 80%, an alert should be triggered.

Thirdly, auto-scaling is another essential feature in managing cloud resources. It allows automatic adjustment of computational resources based on demand, ensuring efficient use of resources while maintaining application performance.

Lastly, regular audits are necessary to identify underutilized or idle resources which can be decommissioned to save costs without affecting performance.

Moreover, cloud’s pay-as-you-go model reduces upfront costs associated with infrastructure setup and maintenance. This allows organizations to focus more on development efforts rather than managing infrastructure.

Furthermore, cloud providers often have global data centers allowing for easy distribution of applications to users worldwide. This enhances user experience by reducing latency and improving availability.

Lastly, cloud environments support containerization technologies like Docker and Kubernetes, which are integral to modern DevOps practices. Containers provide an isolated environment for application execution, ensuring consistency across different stages of the deployment pipeline.

12. Explain how you would architect a secure cloud-based environment.

A secure cloud-based environment can be architected by implementing a multi-layered security approach. At the infrastructure level, use firewalls and intrusion detection systems to protect against external threats. Implement strong access controls with two-factor authentication for all users. Encrypt data at rest and in transit using industry-standard protocols like SSL/TLS.

For application-level security, follow best practices such as principle of least privilege (PoLP), where each user is given minimum permissions necessary to perform their tasks. Regularly update and patch applications to fix vulnerabilities.

Ensure compliance with regulations like GDPR or HIPAA depending on your business needs. Use logging and monitoring tools to detect anomalies and respond quickly to incidents.

Consider using a Cloud Access Security Broker (CASB) to enforce security policies across multiple cloud services. Lastly, conduct regular audits and penetration testing to identify potential weaknesses and improve security measures.

13. How do you design for high availability and fault tolerance in the cloud?

Designing for high availability and fault tolerance in the cloud involves several key strategies. Redundancy is crucial, achieved by deploying multiple instances of resources across different zones or regions to ensure service continuity if one fails. Load balancing helps distribute traffic evenly among these instances, preventing overloading and potential failure. Auto-scalaling adjusts resource allocation based on demand, ensuring optimal performance while minimizing costs. Regular backups and disaster recovery plans are essential to quickly restore services after a catastrophic event. Monitoring systems provide real-time insights into system health, enabling proactive issue resolution before they escalate into failures.

14. What are some of the potential pitfalls to avoid when implementing cloud storage?

Cloud storage implementation can face several pitfalls. One is the risk of data breaches, as cloud storage often involves third-party services which may not have robust security measures. Another pitfall is vendor lock-in, where a company becomes overly dependent on one provider and finds it difficult to switch due to compatibility issues or high switching costs. Data loss is another concern, especially if the provider does not offer adequate backup solutions. Additionally, there could be regulatory compliance issues depending on the nature of the stored data. Lastly, cost overruns can occur if usage isn’t monitored closely, leading to unexpected charges.

15. Can you describe how to utilize containerization in cloud computing?

Containerization in cloud computing involves encapsulating an application and its dependencies into a container. This process begins with choosing a suitable base image, which is then customized by adding the necessary libraries and dependencies required for the application to run. The Dockerfile, a text document that contains all the commands needed to build a container image, is created next. Once the Dockerfile is ready, it’s used to create the container image using the ‘docker build’ command.

The resulting container can be deployed on any system that supports Docker, ensuring consistency across different environments. Containers are lightweight and start quickly, making them ideal for scaling applications. They also provide isolation, as each container runs in its own user space, preventing interference between applications.

In terms of management, orchestration tools like Kubernetes can be used. These tools help manage containers at scale, handling tasks such as deployment, networking, scaling, and availability.

16. What is “elasticity” in the context of cloud computing and why is it important?

Elasticity in cloud computing refers to the system’s ability to adapt to workload changes by provisioning and de-provisioning resources in an autonomic manner, enabling businesses to scale up or down based on demand. This is crucial as it allows for cost efficiency; companies only pay for what they use. It also ensures high availability and performance because during peak times, additional resources can be allocated to handle the increased load, preventing system overloads or crashes. Furthermore, elasticity supports business growth without requiring significant upfront investment in infrastructure.

17. Can you discuss your experience with serverless architecture?

In my previous role as a cloud engineer, I extensively used serverless architecture. My primary responsibility was to design and implement AWS Lambda functions for microservices-based applications. This eliminated the need for managing servers, thus reducing operational costs and complexity.

I also utilized Amazon API Gateway for creating, deploying, and managing APIs. It seamlessly integrated with Lambda, providing an efficient execution model. Additionally, I implemented DynamoDB, a NoSQL database service, which further enhanced our application’s performance by offering low latency at any scale.

Moreover, I have experience in setting up CI/CD pipelines using AWS CodePipeline and CodeBuild for automating deployment processes. This ensured that our code changes were reliably delivered to production.

My exposure to serverless architecture has not only improved scalability but also accelerated development cycles due to its event-driven nature.

18. How would you ensure compliance with data protection regulations in a cloud environment?

To ensure compliance with data protection regulations in a cloud environment, it’s crucial to implement several strategies. First, understand the specific regulations applicable to your industry and region such as GDPR or HIPAA. Then, select a cloud service provider that offers robust security measures including encryption, intrusion detection, and regular audits. Implement access controls to limit who can view sensitive data. Regularly monitor and audit data usage and handling practices. Use tools for automatic compliance monitoring and reporting. Lastly, have an incident response plan ready for potential breaches.

19. How can you use cloud services to effectively manage big data?

Cloud services can effectively manage big data through scalable storage and processing capabilities. They offer flexible, on-demand resources that can handle the volume, velocity, and variety of big data. Cloud-based platforms like Hadoop or Spark provide distributed computing power for large-scale data analysis. These platforms use parallel processing to analyze massive datasets quickly.

Moreover, cloud services also offer tools for data ingestion, transformation, and integration such as AWS Glue or Google Cloud Dataflow. These tools automate the process of preparing and combining data from different sources.

Additionally, cloud providers offer managed database services (like Amazon RDS or Google BigQuery) which are optimized for handling big data workloads. These services take care of tasks like hardware provisioning, setup, configuration, and backups, allowing users to focus more on analyzing data rather than managing infrastructure.

Furthermore, Machine Learning and AI services provided by cloud platforms enable predictive analytics on big data. This helps in deriving insights and making informed decisions.

20. Can you describe how to optimize costs when using cloud services?

Optimizing costs in cloud services involves several strategies. First, understanding the pricing model of your provider is crucial. This includes knowing when you’re billed and for what resources. Second, utilizing auto-scaling features can help manage costs by adjusting resource usage based on demand. Third, consider reserved instances for long-term workloads as they often come at a discounted rate. Fourth, regularly review and monitor your service usage to identify any unnecessary expenditures. Fifth, use cost management tools provided by your cloud service provider to track spending. Lastly, deleting unused or idle resources also helps reduce costs.

21. What are some factors to consider when choosing between public, private, and hybrid clouds?

When choosing between public, private, and hybrid clouds, several factors come into play. Cost is a significant consideration; public clouds often have lower upfront costs but may not offer the same level of control as private clouds. Private clouds provide more customization options and security, but at a higher cost. Hybrid clouds balance these aspects by combining public and private cloud features.

Data sensitivity also influences this decision. For highly sensitive data, private clouds are preferable due to their enhanced security measures. However, for less sensitive data, public clouds can be an economical choice.

Performance needs should also be considered. If high performance is required, private or hybrid clouds might be better suited due to their dedicated resources.

Scalability is another factor. Public clouds typically offer greater scalability than private ones, making them ideal for businesses expecting growth.

Lastly, regulatory compliance can dictate the choice. Certain industries require strict data handling procedures that only private clouds can provide.

22. Explain how to ensure cloud systems are scalable.

Scalability in cloud systems is achieved through effective design and implementation strategies. The first step involves selecting a scalable cloud service model, such as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), or Software as a Service (SaaS). These models provide the flexibility to scale resources up or down based on demand.

Next, implement auto-scaling features that automatically adjust capacity to maintain steady performance levels. This can be done using tools provided by cloud service providers like AWS Auto Scaling or Google Cloud’s Compute Engine Autoscaler.

Load balancing is another crucial aspect of scalability. It distributes network traffic across multiple servers to ensure no single server becomes overwhelmed. Load balancers can be either software-based or hardware-based.

Finally, consider implementing microservices architecture. Microservices allow for independent scaling of different parts of an application, providing more granular control over resource allocation.

Monitoring system performance regularly helps identify potential bottlenecks and areas where scaling may be required. Tools like Amazon CloudWatch or Azure Monitor can assist with this.

23. How would you design a disaster recovery plan for cloud-based systems?

A disaster recovery plan for cloud-based systems should be designed with a focus on data redundancy, failover procedures, and regular testing.

Data redundancy is crucial to ensure no loss of information during a disaster. This can be achieved by maintaining multiple copies of data across different geographical locations within the cloud environment.

Failover procedures are necessary to maintain system availability during a disaster. These procedures involve automatic switching from the primary system to a standby system when a failure or disruption occurs. The design of these procedures should consider factors such as the time it takes to switch over and the capacity of the standby system.

Regular testing of the disaster recovery plan is essential to identify any potential issues and make necessary adjustments. Testing should simulate various disaster scenarios to assess the effectiveness of the plan under different conditions.

24. What is your experience with cloud automation and orchestration tools?

I have extensive experience with cloud automation and orchestration tools, primarily focusing on AWS CloudFormation and Terraform. I’ve used AWS CloudFormation for automating the deployment of AWS resources, creating stacks of resources based on templates written in JSON or YAML. This has allowed me to manage infrastructure as code, ensuring consistency and repeatability.

In addition, I’ve utilized Terraform extensively due to its provider-agnostic approach. It allows managing a wide variety of services from different providers within one workflow. My work involved writing declarative configuration files which are then executed by Terraform to create, update, or destroy resources.

Furthermore, I’ve also worked with Kubernetes for container orchestration, deploying and managing microservices-based applications across clusters of hosts.

25. Can you discuss your methods for assessing the performance of a cloud service provider?

In assessing a cloud service provider’s performance, I focus on several key areas.

Firstly, availability and reliability are crucial; the uptime guarantee provided by the service level agreement (SLA) is evaluated. A high percentage indicates better service continuity.

Secondly, scalability is assessed to ensure that the provider can handle increased workloads when necessary. This includes evaluating their infrastructure and ability to provide additional resources quickly.

Thirdly, security measures implemented by the provider are examined. This involves reviewing their data encryption methods, compliance certifications, and physical security measures at data centers.

Fourthly, I consider the speed of the service, including latency and bandwidth. These factors directly impact user experience and productivity.

Lastly, customer support quality is important. The provider should have a responsive and knowledgeable team available 24/7.

cloud computing assignment questions and answers

4. What are the different versions of the cloud?

There are two primary deployment models of the cloud: Public and Private . 

  • Public  Cloud: The set of hardware, networking, storage, services, applications, and interfaces owned and operated by a third party for use by other companies or individuals is the public cloud. These commercial providers create a highly scalable data center that hides the details of the underlying infrastructure from the consumer. Public clouds are viable because they offer many options for computing, storage, and a rich set of other services.
  • Private Cloud: The set of hardware, networking, storage, services, applications, and interfaces owned and operated by an organization for the use of its employees, partners, or customers is the private cloud. This can be created and managed by a third party for the exclusive use of one enterprise. The private cloud is a highly controlled environment not open for public consumption. Thus, it sits behind a firewall.
  • Hybrid Cloud: Most companies use a combination of private computing resources and public services, called the hybrid cloud environment. 
  • Multi-Cloud: Some companies, in addition, also use a variety of public cloud services to support the different developer and business units – called a multi-cloud environment.

5. What are the main constituents that are part of the cloud ecosystem?

The parts of the cloud ecosystem that determine how you view the cloud architecture are:

  • Cloud consumers
  • Direct customers
  • Cloud service providers
  • Software Dev
  • Data Science

6. Who are the Cloud Consumers in a cloud ecosystem?

The individuals and groups within your business unit that use different types of cloud services to get a task accomplished. A cloud consumer could be a developer using compute services from a public cloud.

7. Who are the Direct customers in a cloud ecosystem?

Users who often take advantage of services that your business has created within a cloud environment. The end-users of your service have no idea that you’re using a public or private cloud. As long as the users are concerned, they’re interacting directly with the services and value.

8. Who are the Cloud service providers in a cloud ecosystem?

Cloud service providers are the commercial vendors or companies that create their own capabilities. The commercial vendors sell their services to cloud consumers. In contrast to this, a company might decide to become an internal cloud service provider to its own partners, employees, and customers, either as an internal service or as a profit center. Cloud service providers also create applications or services for such environments.

9. Describe the Cloud Computing Architecture.

The cloud computing architecture is all the components of a cloud model that fit together from an architectural perspective. The figure below depicts how the various cloud services are related to support the needs of businesses. On the left side, the cloud service consumer represents the types of uses of cloud services. No matter what the requirements of the particular constituent are, it is important to bring the right type of services together that can support both internal and external users. Management of the consumers should be able to make services readily available to support the changing business needs. The applications, middleware, infrastructure, and services that are built based on on-premises computing models are within this category. In addition to this, the model depicts the role of a cloud auditor. This organization provides an oversight either by an internal or external group which makes sure that the consumer group meets its obligations.

cloud computing assignment questions and answers

10. What are the Cloud Storage Levels?

Cloud storage device mechanisms provide common levels of data storage, such as:

  • Files – These are collections of data that are grouped into files that are located in folders.
  • Blocks – A block is the smallest unit of data that is individually accessible. It is the lowest level of storage and the closest to the hardware.
  • Datasets – Data sets organized into a table-based, delimited, or record format.
  • Objects – Data and the associated metadata with it are organized as web-based resources.

Each of the above data storage levels is associated with a certain type of technical interface. This interface corresponds to a particular type of cloud storage device and the cloud storage service used to expose its API.

Cloud Computing Interview Questions for Experienced

1. what are serverless components in cloud computing.

Serverless components in cloud computing allow the building of applications to take place without the complexity of managing the infrastructure. One can write code without having provision to a server.

Serverless machines take care of virtual machines and container management. Multithreading, hardware allocating are also taken care of by the serverless components. 

2. What are the advantages and disadvantages of serverless computing?

Serverless computing has the following advantages and disadvantages: Advantages:

  • It is cost-effective.
  • The operations on serverless computing are simplified.
  • Serverless computing helps boost productivity.
  • It offers scaling options.
  • It involves zero server management.

Disadvantages:

  • Serverless code can cause response latency.
  • It is not ideal for high-computing operations because of resource limitations.
  • For serverless computing, the responsibility of security comes under the service company and not the consumer, which might be more vulnerable.
  • Debugging serverless code is a bit more challenging.

3. What are cloud-enabling technologies?

There are several areas of technology that contribute to modern-day cloud-based platforms. These are known as cloud-enabling technologies. Some of the cloud-enabling technologies are:

  • Broadband Networks and Internet Architecture
  • Data Center Technology
  • (Modern) Virtualization Technology
  • Web Technology
  • Multitenant Technology
  • Service Technology

4. What are Microservices?

Microservices is a process of developing applications that consist of code that is independent of each other and of the underlying developing platform. Each microservice runs a unique process and communicates through well-defined and standardized APIs, once created. These services are defined in the form of a catalog so that developers can easily locate the right service and also understand the governance rules for usage.

5. Why are microservices important for a true cloud environment?

The reason why microservices are so important for a true cloud environment is because of these four key benefits:

  • Each microservice is built to serve a specific and limited purpose, and hence application development is simplified. Small development teams can then focus on writing code for some of the narrowly defined and easily understood functions.
  • Code changes will be smaller and less complex than with a complex integrated application, making it easier and faster to make changes, whether to fix a problem or to upgrade service with new requirements.
  • Scalability — Scalability makes it easier to deploy an additional instance of a service or change that service as needs evolve.
  • Microservices are fully tested and validated. When new applications leverage existing microservices, developers can assume the integrity of the new application without the need for continual testing.

6. What is the cloud usage monitor?

The cloud usage monitor mechanism is an autonomous and lightweight software program that is responsible for collecting and processing the IT resource usage data.

Cloud usage monitors can exist in different formats depending on what type of usage metrics these are designed to collect and how the usage data needs to be collected. The following points describe 3 common agent-based implementation formats.

  • Monitoring Agent
  • Resource Agent
  • Polling Agent

7. How does the Monitoring Agent monitor the cloud usage?

An intermediary and an event-driven program that exists as a service agent and resides along the existing communication paths is a monitoring agent.  It transparently monitors and analyzes dataflows. Commonly, the monitoring agent is used to measure the network traffic and also message metrics.

8. How does the Resource Agent monitor the cloud usage?

A processing module that is used to collect usage data by having event-driven interactions with the specialized resource software, is a resource agent. This agent is applied to check the usage metrics based on pre-defined, observable events at the resource software level, like initiating, suspending, resuming, and vertical scaling.

9. How does the Polling Agent monitor cloud usage?

A processing module that gathers cloud service usage data by polling IT resources is called a polling agent. The polling agent has also been used to timely monitor the IT resource status, like uptime and downtime. Each of these can be designed to forward collected usage data to a log database for post-processing and for reporting purposes.

10. What are Cloud-Native Applications?

‘Cloud native’ is a software framework designed with containers, microservices, dynamic orchestration, and also continuous delivery of software. Every part of the cloud-native application has within it its own container and is dynamically orchestrated with other containers to optimize the way the resources are utilized.

11. How does the Cloud Native Computing Foundation define cloud-native applications?

The Cloud Native Computing Foundation gives a clear definition of cloud-native:

  • Container packaged: This means a standard way to package applications that is resource-efficient. By using a standard container format, more applications can be densely packed.
  • Dynamically managed: This means a standard way to discover, deploy, and scale up and down containerized applications.
  • Microservices oriented: This means a method to decompose the application into modular, independent services that interact through well-defined service contracts.

12. What is meant by Edge Computing?

Edge and cloud are complementary. These are both parts of a broader concept called the distributed cloud. A majority of those pursuing edge computing strategies are now viewing edge as part of their overall cloud strategy.

Edge computing, unlike cloud computing, is all about the physical location and issues related to latency. Cloud and edge combine the strengths of a centralized system, along with the advantages of distributed operations at the physical location where things and people connect. In IoT scenarios, the edge is very common. Cloud is different from the edge, in that it has never been about location. As opposed, it has always been about the independence of location.

The popular scenarios are where you have cloud and edge together, and the cloud provider controls to run and defines the architecture for what is out at the edge.

13. What is an API Gateway?

An API gateway allows multiple APIs to act together as a single gateway to provide a uniform experience to the user. In this, each API call is processed reliably. The API gateway manages the APIs centrally and provides enterprise-grade security. Common tasks of the API services can be handled by the API gateway. These tasks include services like statistics, rate limiting, and user authentication.

14. What do you mean by Rate Limiting?

Rate Limiting is a way to limit the network traffic. Rate limiting runs within the app rather than the server. It typically tracks the IP addresses and the time between each request.

It can eliminate certain suspicious and malicious activities. Bots that impact a website can also be stopped by Rate Limiting. This protects against API overuse which is important to prevent. 

15. What do you mean by encapsulation in cloud computing?

A container is a packaged software code along with all of its dependencies so that it can run consistently across clouds and on-premises. This packaging up of code is often called encapsulation. Encapsulating code is important for developers as they don’t have to develop code based on each individual environment.

16. What are the different Datacenters deployed for Cloud Computing?

Cloud computing is made up of various data centers put together in a grid form. It consists of the data centers like:

  • Containerized Data Centers
  • Low-Density Data Centers

17. What are Containerized Data Centers?

Containerized Data Centers are the traditional data centers that allow a high level of customization with servers, mainframes, and other resources. These require planning, cooling, networking, and power to access and work.

18. What are Low-Density Data Centers?

Low-Density Data Centers are optimized to give high performance. The space constraint is being removed and there is an increased density in these data centers. One drawback it has is that with high density the heat issue also creeps in. These data centers are quite suitable to develop the cloud infrastructure.

19. What are some issues with Cloud Computing?

Following are some of the issues of cloud computing:

  • Security Issues : As it would be in any other computing paradigms, security is as much of a concern as Cloud computing. Cloud Computing is vaguely defined as the outsourcing of services, which in turn causes users to lose significant control over their data. With the public Cloud, there is also a risk of seizure associated.
  • Legal and Compliance Issues : Sometimes, clouds are bounded by geographical boundaries. The provision of different services is not location-dependent. Because of this flexibility Clouds face Legal & Compliance issues. Though these issues affect the end-users, they are related mainly to the vendors.
  • Performance and Quality of Service (QoS) Related Issues : Paradigm performance is of utmost importance for any computing. The Quality of Service (QoS) varies as the user requirements may vary. One of the critical Quality of Service-related issues is the optimized way in which commercial success can be achieved using Cloud computing. If a provider is unable to deliver the promised QoS it may tarnish its reputation. One faces the issue of Memory and Licensing constraints which directly hamper the performance of a system, as Software-as-a-Service (SaaS) deals with the provision of software on virtualized resources,
  • Data Management Issues : An important use case of Cloud Computing is to put almost the entire data on the Cloud with minimum infrastructure requirements for the end-users. The main problems related to data management are scalability of data, storage of data, data migration from one cloud to another, and also different architectures for resource access. It is of utmost importance to manage these data effectively, as data in Cloud computing also includes highly confidential information.

20. How does Resource Replication take place in Cloud Computing?

Resource Replication is the creation of multiple instances of the same IT resource. It is typically performed when an IT resource’s availability and performance are needed to be enhanced. The virtualization technology is adopted to implement the resource replication mechanism in order to replicate the cloud-based IT resources.

cloud computing assignment questions and answers

Conclusion:

Cloud computing is completely based on the Internet. It is the next stage in the evolution of the Internet. Cloud computing uses the cloud that provides the way to deliver the services whenever and wherever the user needs them. Enterprises use cloud computing to provide solutions to the needs of their customers, partners, and providers.

Cloud computing includes partners, vendors, and business leaders as the three major contributors. The vendors provide applications and their related technology, infrastructure, hardware, and integration. The partners offer cloud services and provide support services to the customers. The business leaders evaluate the cloud service provided by the partners.  Cloud computing enables enterprises to treat their resources as a pool and not as independent resources.
