WHAT IS CLOUD COMPUTING

What is a Cloud?A web based pool of shared computing resources such as software and data storage.

Cloud computing ::• Emerging computing technology that uses the internet and central remote servers to maintain data and applications.• An internet based computing environment where you pay only for resources that you use• Anything that involves delivering hosted services over the Internet. • Allows access to services without user technical knowledge or control of supporting infrastructure

Full-Virtualization

Full virtualization is a technique in which a complete installation of one machine is run on another. The result is a system in which all software running on the server is within a virtual machine.

Para-Virtualization

Para-virtualization allows multiple operating systems to run on a single hardware device at the same time by more efficiently using system resources, like processors and memory.

Windows O/S ,Linux O/S & modern O/S.

Types of Clouds

• Public cloud• Private cloud• Hybrid cloud

• Private: Data center that supplies hosted services to a limited number of people

• Public: Sells services to anyone on the Internet.

• Example:- Amazon Web Services is the largest public cloud provider.

• Hybrid : A hybrid cloud is typically offered in one of two ways:

-a vendor has a private cloud and forms a partnership with a public cloud provider

- a public cloud provider forms a partnership with a vendor that provides private cloud platforms.
