Cloud computing is a revolution in IT that provides great job opportunities. It uses shared computing resources over the Internet instead of local servers or personal devices. There are different types of cloud including public, private, and hybrid. Cloud services include SaaS, PaaS, and IaaS. Cloud provides advantages like scalability, availability, and pay-per-use which reduces costs. Major cloud providers are expanding offerings and making acquisitions. Cloud jobs are expected to grow significantly in coming years.

3. WHAT IS CLOUD
COMPUTING

4. 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

5. 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.

6. 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.

7. Types of Clouds
• Public cloud
• Private cloud
• Hybrid cloud

8. • 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.
