Cloud Computing Interview Questions Answers

What is the use of APIs in cloud services?

API’s (Application Programming Interface) is very useful in cloud platforms.

  • It eliminates the need to write the fully fledged programs
  • It provides the instructions to make communication between one or more applications
  • It allows easy creation of applications and link the cloud services with other systems

What are the different data centers deployed for cloud computing?

Cloud computing consists of different datacenters like

  • Containerized Datacenters
  • Low Density Datacenters

In cloud computing what are the different layers?

The different layers of cloud computing are:

  • SaaS: Software as a Service (SaaS), it provides users access directly to the cloud application without installing anything on the system.
  • IaaS: Infrastructure as a service, it provides the infrastructure in terms of hardware likememory, processor speed etc.
  • PaaS: Platform as a service, it provides cloud application platform for the developers

How important is the platform as a service?

Platform as a service or PAAS is an important layer in cloud computing. It provides applicationplatform for providers. It is responsible for providing complete virtualization of the infrastructurelayer and makes it work like a single server.

What is a cloud service?

Cloud service is used to build cloud applications using the server in a network through internet. Itprovides the facility of using the cloud application without installing it on the computer. It alsoreduces the maintenance and support of the application which are developed using cloud service.

List down the three basic clouds in cloud computing?

  • Professional cloud
  • Personal cloud
  • Performance cloud

As a infrastructure as a service what are the resources that are provided by it?

IAAS ( Infrastructure As A Service) provides virtual and physical resources that are used to build acloud. It deals with the complexities of deploying and maintaining of the services provided by thislayer. Here the infrastructure is the servers, storage and other hardware systems.

What are the business benefits involved in cloud architecture?

The benefits involved in cloud architecture is

  • Zero infrastructure investment
  • Just in time infrastructure
  • More efficient resource utilization

What are the characteristics of cloud architecture that separates it from tradition alone?

The characteristics that makes cloud architecture above traditional architecture is

  • According to the demand cloud architecture provides the hardware requirement
  • Cloud architecture is capable of scaling the resource on demand
  • Cloud architecture is capable of managing and handling dynamic workloads without failure
