Cloud computing is a technology that uses remote servers and the internet to maintain data and applications. This allows users to access files and applications from any device with an internet connection. Cloud computing provides efficient computing by centralizing storage, memory, processing and bandwidth. There are different types of cloud computing models including Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS) as well as public, private, hybrid and community cloud types. The document discusses the advantages of cloud computing such as reliability, scalability, and reduced maintenance, as well as disadvantages around security, dependency, and cost.

2. What Is Cloud Computing:-
 Technology that uses
the internet and central
remote servers to
maintain data and
applications.
 allows consumers and
businesses to use
applications without
installation and access
their personal files at
any computer with
internet access.
 This technology allows
for much more efficient
computing by
centralizing storage,
memory, processing and
bandwidth.

3. Example of Cloud
Computing:-

4. Characteristics:-
 Autonomic computing
 Client–server model
 Grid computing
 Mainframe computer
 Utility computing
 Peer-to-peer

5. Classification of Cloud on the
basis of service provided

6. Software as a service
(SaaS)
This is the most common
form of cloud computing
which we see in action. It
is a complete software
offering on the cloud.
They are accessed by the
customers on pay per use
basis.
Example:-
Gmail , Hotmail etc

7. Platform as a service
(PaaS)
The consumer creates the
software using tools and
libraries from the provider.
The consumer also
controls software
deployment and
configuration settings. The
provider provides the
networks, servers and
storage .
Example:-
Wavemaker,Longjump etc

8. Infrastructure as a service
(IaaS)
Hardware related services
are provided using the
principles of Cloud
Computing. These include
disk storage and virtual
servers.
Amazon EC2, Amazon S3,
Rackspace Cloud Servers
are some of the leading
vendors.

9. Cloud Computing
classified basis of location
 Public Cloud
 Private Cloud
 Hybrid Cloud
 Community Cloud

10. Public Cloud
Computing infrastructure is
hosted at the vendor’s
premises. The customer has
no visibility over the location of
the cloud computing
infrastructure. The computing
infrastructure is shared
between organizations.

11. Private Cloud
Computing architectu
re is dedicated to the
customer and is not
shared with other
organisations.Private
clouds may be
externally hosted
ones as well as in
premise hosted
clouds.

12. Hybrid Cloud
Organisations host
some critical, secure
applications in private
clouds. The not so
critical applications are
hosted in the public
cloud. The combination
is known as Hybrid
Cloud.

13. Community Cloud
The
cloud infrastructure i
s shared between
the organizations of
the same
community.

14. Cloud Computing Types:-

15. Advantages:-
 Reliability
 Scalability
 Performance
 Security
 Maintenance
 Virtualization
 Multi-tenancy

16. Disadvantages:-
 Security & Privacy
 Dependency (loss
of control)
 Cost
 Decreased
flexibility
 Knowledge And
Integration
