Cloud Computing Interview Questions: Cloud Computing has now become a must know information technology paradigm for most of the entrepreneurs. If you are willing to build your own startup and do not know anything about cloud computing, then it would surely be a weakness for your startup.

For your thorough understanding of cloud computing, the first step is to understand the basics of Cloud Computing. We are bringing you those Cloud Computing FAQs, which you must know. Whether you’re going to build your own startup or even if you are just going for an interview. These Frequently Asked Questions would certainly help you.

Also, these FAQs will clear many doubts you have regardless of your position in the industry. Also, these cloud computing interview questions, answer some of the questions most of you have.

Interview Questions On Cloud Computing

What is Cloud Computing?

Cloud computing is the way to access the files which are over the internet (cloud) in the way ‘Pay Per Use’. The data is differentiated in types as servers, storage, databases, software, etc. Users can access the data based on their demands. Companies offering cloud services are called cloud service providers.

We have written one separate article on the definition itself. Feel free to check out.

What are the service models of Cloud  Computing?

Cloud computing services have the following types

  • IaaS
  • PaaS
  • SaaS

IaaS :

Infrastructure as a Service abbreviated as IaaS is the most basic type. In this type, other companies (third parties) holds the cloud computing elements like servers, networking, storage, software. They do also provide security, backup, and Maintainance.

PaaS :

Platform as a Service (PaaS) is another cloud computing service in which there is the elimination of complexity of buying and managing the hardware layers.  This type of cloud computing allows users to develop applications without the need to look into the code, hardware, and other things.

SaaS :

Abbreviated as SaaS, Software as a Service is a method of delivering the services over the cloud on demand. We may also call this method as ‘Application as a Service’. Usually, in this type user can access the data which is present on another person’s computer via a browser. There is no need to setup or install any application to access that data.

What are the advantages of Cloud Computing?

The cloud offers a few points of interest, some of which may differ in view of the size and sort of business you’re running, the industry you work in and where you are changing your business.

For new companies, the cloud can offer a fundamental differentiator. It enables anybody with a plan to get their business up and running rapidly with negligible in advance expenses.

The cloud empowers little to medium-sized organizations with constrained assets to exploit industry-driving process, stockpiling and systems administration capacities that they can scale on request as their business develops.

Bigger ventures frequently confront complex difficulties guaranteeing the accessibility and execution of high-activity sites and requesting applications, and in addition foundation prerequisites that change crosswise over offices. The cloud can enable endeavors to build their operational proficiency, profitability, and deftness.

To be specific, Cloud Computing has following advantages:

  • Cost

The cost is much important for any business. Cloud computing certainly reduces the cost of buying the hardware and its management.

  • Adaptability

Cloud computing does allow users to control the code. And do allow adaptable applications.

  • Performance and Speed

The performance surely does improve as the speed also increases if cloud computing is used.

  • Productivity

Productivity is another term which gets benefits from this cloud computing.

  • Security

Cloud computing does also offer more secure environment.

What are the deployment models of Cloud Computing?

There are three ways of deploying the cloud data. Let us see them in brief.

  • Public Cloud
  • Private Cloud
  • Hybrid Cloud

Explain each of the deployment models?

Public Cloud 

Public cloud is when the services are over the network which is open for public access. These services are mostly free. So, being in this model, users don’t need to purchase any hardware or software infrastructure. Also, These are all managed by the cloud service provider. Furthermore, Amazon Web Services (AWS), Microsoft Azure are the examples of the public cloud.

Private Cloud

This deployment model of cloud computing is generally used in single organizations. This can be managed by that organization itself or a third party. This type has more control of resources. The use of this Private Cloud can improve business, but has the possibility of raising issues. So security should not be tolerated.

Hybrid Cloud

Hybrid cloud can be a composition of two clouds mentioned above. Such that, the data can be shared between the public as well as a private type both. Consider an example where the company does not need to have a private cloud to process the temporary data. So for that purpose, the public cloud will be used. The private will also be used for more important data which not a temporary.

What is the Difference Between Cloud and Traditional Storage methods?

Firstly, the traditional data storing methods are costly due to heating and some software/hardware issues. Maintainance cost also increases from time to time which is not the case in Cloud Computing. Also, as mentioned in advantages, scalability makes a huge difference as we cannot predict how much stress would occur on the system at the start itself.

 What are the phases of Cloud Computing?

  1. Launch
  2. Monitor
  3. Shutdown
  4. Cleanup

What are the components in the Architecture of Cloud Computing?

Cloud Computing has these components in its architecture.

The front-end platform consists of a fat client, thin client, mobile device. The back-end platform consists of servers, storage, a cloud-based delivery, and a network (Internet, Intranet, Intercloud).

What are the components of the Windows Azure?

  • Cloud.
  • SQL Database.
  • Windows Azure AppFabric.

Mention some of the services of the Windows Azure.

  • Computation
  • Storage
  • Management

Best Example of open-source Cloud Computing


What are the platforms for performing large-scale computing?

  • mapReduce
  • Apache Hadoop

Give some examples of open source cloud computing platform databases?

The open source cloud computing platform databases are

  • MongoDB
  • CouchDB
  • LucidDB

Give Security management in terms of Cloud Computing.

  • Identity management access provides the authorization of application services.
  • Access control permission is given to the users to have complete controlling access of another user who is entering into the cloud environment.
  • Authentication and Authorization provide access to only the authorized and authenticated users only to access the data and applications.

Define AWS

AWS remains for Amazon Web Service which is a gathering of remote processing administrations otherwise called distributed computing. This innovation of distributed computing is otherwise called IaaS or Infrastructure as a Service.

What is the utilization of API in cloud administrations?

Programming interface’s ( Application Programming Interface) is extremely helpful in cloud stages

  •  It dispenses with the need to compose the completely fledged projects
  • Gives the guidelines to make correspondence between at least one applications
  • It permits simple production of utilization and connection the cloud administrations with different frameworks

These are some cloud computing interview questions. In addition to these, Interviewer can ask you some more questions including the example of CSPs. Finally, If you have any questions, comment below.
