  • List out different layers which define cloud architecture?

The different layers used by cloud architecture are:
CLC or Cloud Controller
Cluster Controller
SC or Storage Controller
NC or Node Controller

Cloud Computing Interview Questions

  • What are system integrators in Cloud Computing?

In Cloud Computing, systems integrator provides the strategy of the complicated process used to design a cloud platform. Integrator allows to create more accurate hybrid and private cloud network, as integrators have all the knowledge about the data center creation.

  • What is “ EUCALYPTUS” stands for?

  • Mention some open source cloud computing platform databases?

The open source cloud computing platform databases are

  • What are the security laws which are implemented to secure data in a cloud ?

The security laws which are implemented to secure data in cloud are

Processing: Control the data that is being processed correctly and completely in an application
File: It manages and control the data being manipulated in any of the file
Output reconciliation: It controls the data which has to be reconciled from input to output
Input Validation: Control the input data
Security and Backup: It provides security and backup it also controls the security breaches logs

Cloud Computing Interview Questions

  • Mention the name of some large cloud providers and databases?

Google bigtable
Amazon simpleDB
Cloud based SQL

  • Explain the difference between cloud and traditional datacenters?

The cost of the traditional data center is higher due to heating and hardware/software issues
Cloud gets scaled when the demand increases. Majority of the expenses are spent on the maintenance of the data centers, while that is not the case with cloud computing

                                                                                                             Cloud Computing Interview Questions

  • Explain what are the different modes of software as a service (SaaS)?

Simple multi-tenancy : In this each user has independent resources and are different from other users, it is an efficient mode.
Fine grain multi-tenancy: In this type, the resources can be shared by many but the functionality remains the same.

  • What is the use of API’s 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 service
with other systems

Cloud Computing Interview Questions

  • 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 like memory, processor speed etc.
PaaS: Platform as a service, it provides cloud application platform for the developers

                                                                                                            Cloud Computing Interview Questions

  • How important is the platform as a service?

a.Platform as a service or PAAS is an important layer in cloud computing. It provides application platform for providers. It is responsible for providing complete virtualization of the infrastructure layer 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. It provides the facility of using the cloud application without installing it on the computer. It also reduces the maintenance and support of the application which are developed using cloud service.

Cloud Computing Interview Questions

  • List down the three basic clouds in cloud computing?

Professional cloud
Personal cloud
Performance cloud

  • As an 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 a cloud. It deals with the complexities of deploying and maintaining of the services provided by this layer. Here the infrastructure is the servers, storage and other hardware systems.

Cloud Computing Interview Questions

  • What are the business benefits involved in cloud architecture?

The benefits involved in cloud architecture is
