Cloud Computing Interview Questions and Answers

Someone has rightly said that interviews are more stressful than the job is. Many times we just wish that we do not have to do that entire one on one session. Do not worry, we are here to scoop you out of the stress that you might be going through for your interview related to Cloud Computing. We have compiled an article for you that will help you nail your interview like a pro.

In the easiest way to explain, cloud computing is nothing but the delivery of computing services such as servers, databases, storage, software, analytics, networking and more over the Internet cloud (“the Cloud”). Companies that offer these computing services are known as cloud providers and usually, charge for these cloud computing services based on the criteria of using just the way how you as an individual is charged for water or electricity at their premises.

Most of the cloud computing services are classified into three broad categories namely:

  • Infrastructure As A Service (Iaas),
  • Platform As A Service (Paas), And
  • Software As A Service (Saas).
  • These services are sometimes called the “cloud computing stack”, for the reason that they are built on top of one another.

  • Authentication and Authorization- It provides access to only the authorized and authenticated personnel to securely access the data and applications.

Q17). Mention what is the difference between elasticity and scalability in cloud computing?

Scalability is a typical characteristic of cloud computing which is used to handle the escalating workload by escalating in proportion amount of resource capacity. By the use of scalability, the architecture provides resources on requirement BA is resources as and when the requirement is being raised by the traffic. On the other hand, Elasticity is a characteristic that provides for the concept of commissioning and decommissioning of thehuge amount of resource capacity dynamically. It is usually measured by the speed by which the resources are coming on demand and the usage of those resources.

Q18). What are Hybrid clouds?

Hybrid clouds are nothing but a combination of public clouds as well as private clouds. It is usually preferred over both the clouds because it applies the most healthy approach to implementation of the cloud architecture.
