 Here is the List of most asked Cloud Computing Interview Questions.

1) What is Cloud Computing?

Cloud computing is an Internet-based and latest computer technology. It is the kind of technology that uses clouds to provide the service. Wherever and whenever the user needs it.  It provides a method to access several servers world wide.

2) What are the benefits of cloud computing?

Here are the  Benefits of cloud computing:

Cost Savings

Security

Flexibility

Mobility

Insight

Increased Collaboration

Quality Control

Disaster Recovery

Loss Prevention

Automatic Software Updates

Competitive Edge

Sustainability

3) What is the cloud?

A cloud helps in delivering computing as a service with a combination of networks, hardware, services, and storage, etc. It has three kinds of users

End users

Business management users

Cloud service provider

4) What are the different data types used in cloud computing?

Different data types used in cloud computing are E-mail, photos, blogs etc. As we know that data is increasing day by day. So it became necessary to have new data types by which we can store it easily.

5) Which are the varrious layers that define cloud architecture?

These are the various layers which define cloud architecture:

CLC or Cloud Controller

Walrus

Cluster Controller

SC or Storage Controller

NC or Node Controller

6) Which platforms are used for large scale cloud computing?

Here are some platforms which are used for large scale cloud computing:

Apache Hadoop

MapReduce

7) What are the different layers of cloud computing?

Three Different Layers used in the hierarchy of cloud computing are :

Infrastructure as a service (IaaS)

It provides cloud infrastructure in terms of hardware like memory, processor, speed, etc.

Platform as a service (PaaS):

PaaS is used by Developer as a cloud application platform

Software as a service (SaaS):

Saas Provides directly cloud application to users without any installation on the computer. These applications remain on the cloud.

8) What do you mean by software as a service?

Software As a Service (SaaS) gives cloud applications like Google is doing. It helps users to save their data on the cloud.

9) What is the platform as a service?

This layer is built on the infrastructure model and provide resources like computers, storage and network. It enables the platform to provide full virtualization of the infrastructure. It helps to make it look like a single server and invisible to the outside world.

10) What is on-demand functionality? How is it provided in cloud computing?

As we know Cloud Computing gives on-demand functionality to virtualized IT resources. It utilises a shared pool to provide configurable resources. 

11) What are the platforms used for large scale cloud computing?

Apache Hadoop and MapReduce are the most common platforms used for large scale cloud computing.

12) What are the different models for deployment in cloud computing?

Private cloud

Public cloud

Hybrid cloud

Community cloud

13) What is the private cloud?

Private cloud is a platform which is fully functional and can be owned, operated, restricted to an organization or an industry. Private clouds are used for keeping the strategic operations and some more other reasons are used to secure. 

14) What is the public cloud?

The public clouds are open. These are the clouds that are made for the public’s use and deployment. For eg: Google and Amazon etc.

15) What is a Hybrid Cloud?

Hybrid cloud is a combination of both public and private cloud. It applies a strong approach to execute cloud architecture. It includes the functions and features of both. 

16) What is the difference between cloud computing and mobile computing?

Mobile and cloud computing are somewhat the same thing. Mobile computing uses the concept of cloud computing. Cloud Computing provides the user the data which is required in mobile computing applications run on the remote server. And it gives the user access for storage and manages.

17) What is the difference between Scalability and Elasticity?

Scalability is a feature of cloud computing which is used to handle the workload. Scalability provides the architecture on-demand resources if the requirement is being raised by the traffic.

Whereas, Elasticity is a characteristic which provides the concept of engaging a large amount of resource capacity dynamically. It is measured by the speed by which the resources are coming on demand and the usage of the resources.

18) What are the security Benefits of Cloud Computing?

Cloud computing allows application service.

 It is also used in identity management. 

It gives permission to its users so that they can control the access of other users who are entering in the cloud environment.

19) What is the usage of utility computing?

Utility computing is a plug-in managed by an organization which decides what type of services has to be deployed from the cloud. It facilitates users to pay only for what they use.

20) What is "EUCALYPTUS"? Why is it Used in Cloud Computing?

This Eucalyptus is not a Plant here. It is an acronym. Its full form stands for ‘Elastic Utility Computing Architecture For Linking Your Program To Useful Systems’. It is an open source software which is used in cloud computing and to implement clusters in cloud computing platform as well.
