  • Access Control: The user needs permission so that they can control the access of another user who is entering into the cloud environment.
  • Authentication and Authorization: Allows only the authorized and authenticated the user only to access the data and applications

Q.17  What are system integrators in Cloud Computing?

Ans. The system integrator provides the strategy of the complicated process used to design a cloud platform. The integrator provides information about the data centre creation. Integrator allows creating more accurate hybrid and private cloud network, as integrators have all the knowledge about the data centre creation.

Q.18 What is “EUCALYPTUS” stands for?

Ans. “EUCALYPTUS” is Elastic Utility Computing Architecture which is used for linking the Programs to Useful Systems”

Q.19 Explain what is the use of “EUCALYPTUS” in cloud computing?

Ans. EUCALYPTUS has an open source software infrastructure in cloud computing. It is used to add clusters in cloud computing platform. With the help of EUCALYPTUS public, private, and hybrid cloud can be built. It can produce it’s own data centres. Moreover, it can allow you to use its functionality to many other organizations.

4. Cloud Computing Interview Questions for Expert

The set of Cloud computing interview questions will help you to brush up your knowledge:

Q.21 Name some open source cloud computing platform databases?

Ans. Examples of open source cloud computing platform database are MongoDB, CouchDB, LucidDB.

Q.22 What are the examples of large cloud provider and databases?

Ans.  These are some Cloud providers:

  • Google BigTable
  • Amazon SimpleDB
  • Cloud-based SQL

Q.23  What are the different modes in Software as a Service (SaaS)?

Ans. This is SaaS modes:

  • Simple Multi-tenancy- In this mode, the user is different from the other user and has an independent resource. It is one of the efficient modes.
  • Fine grain multi-tenancy- The resources can be shared by many users, however, the functionality remains the same.

Q.24 Why API’s is used in cloud services?

Ans. API is used in cloud platform because-

  • It provides ease where the user doesn’t need to write the fully fledged program.
  • It helps to make communication between one or more applications.
  • Creates applications which further link the cloud services with other systems.

Q.25 Before going for cloud computing platform what are the essential things to be taken in concern by users?

Ans. Following are the essential things, which can be taken in concern:

  • Compliance
