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.
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.
