2. Introduction:
Cloud computing is a location-independent computing, whereby
shared servers provide resources, software, and data to computers
and other devices on demand.
The term "cloud" is used as a metaphor for the Internet, based on
the cloud drawing used in the past to represent the telephone
network.
Cloud computing describes both a platform and a type of
application. A cloud computing platform dynamically provisions,
configures, reconfigures, and deprovisions servers as needed.
Cloud applications are applications that are extended to be
accessible through the Internet.

3. What is Cloud Computing ?
Cloud computing is a technology that uses the internet and
central remote servers to maintain data and applications.
Cloud computing 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.

4. Representation of a cloud:

5. Types of Cloud
1. Public Cloud
2. Community Cloud
3. Hybrid Cloud
4. Private Cloud

6. PUBLIC CLOUD
 Public Cloud is also known as External cloud
 Public Cloud describes cloud computing in the
traditional main stream sense, whereby resources
are dynamically provisioned on a fine-grained, self-
service basis over the Internet

7. COMMUNITY CLOUD
A community cloud may be established where several
organizations have similar requirements and seek to
share infrastructure .
Examples of community cloud include Google's "Gov
Cloud”.

8. HYBRID CLOUD
 The term "hybrid cloud" is probably the use of physical
hardware and virtualized cloud server instances together to
provide a single common service.
 The term “Hybrid Cloud” is also used to mean as either two
separate clouds joined together (public, private, internal or
external)

9. PRIVATE CLOUD
 Private cloud is also known as Internal cloud
 In Private Cloud users have to buy there own servers, build
them and manage them.

10. KEY FEATURES
 Agility improves with users' ability to rapidly and inexpensively re-
provision technological infrastructure resources
 Cost is claimed to be greatly reduced and capital expenditure is
converted to operational expenditure
 Device and location independence enable users to access
systems using a web browser regardless of their location or what
device they are using (e.g., PC, mobile).
 Multi-tenancy enables sharing of resources and costs across a
large pool of users
 Maintenance of cloud computing applications is easier, since they
don't have to be installed on each user's computer.

11. ISSUES
Privacy:
The companies hosting the cloud services control, and thus, can
monitor the communication and data stored between the user
and the host company.
Availability and performance :
The companies hosting the cloud services control, and thus, can
monitor the communication and data stored between the user
and the host company.
