What is CLOUD COMPUTING?
Cloud computing
is the technology of which is based on the internet media. With the help of
this methodology many servers offers software applications, resources and information
to the computers and devices attached on request with the control of
electricity grid. It is known as the service architectures or virtualization for
improving the utility of the computational techniques. The System is
service oriented and customer focused. Complete detail is taken from the customer
and delivers the service according to the need. The main idea of cloud
computing is based on the cloud that is specifically designed for the processing
each related device is present in this cloud of network. Could computing
remains invisible to the customers’ .They only have to pay for their resource
that they use in cloud computing service.
How cloud computing works:
Cloud
computing involves the multiple cloud components that communicate with each
other with the help of application interfaces mostly web services. UNIX
operating system follows the same theoretical techniques for its tasks. The
task complexity is divided into all the components making balanced and
manageable results. The two most important components of the back end and front
end .the front end is the interfaces or the main screen that is visible to the
customers and users through which they interact with the system. This interface
can be browsed with the help of web browsers and all the applications can be
used with this interface. Usually this interface is GUI based. The back end
involves all the components and the complete architecture and programming
technique of cloud computing that is totally remains hidden from the users.
Only system known what is going one at the back of very user request. The back
end device involves, cloud server, Assistant computers, Data storage media and
many connectors.
Historical background
The very
first concept for the cloud computing was given by the John McCathy in 1960s.he
first gave the statement for the future use of computational techniques as a
public utility. With the arrival of the Virtual private networks this concept
which was modernized in 1966 took implementation shape in year 2007 the most
famous organization such as Google ,IBM and may universities worldwide started
research program on cloud computing and finally in 2008 the first cloud
computing system was introduced.
Advantages of the cloud computing :-
1) Agile functionalities: Cloud
computing enables user to frequently use the technological resource at
inexpensive price.
2) Application interface for users:
Another great feature plus advantage of cloud computing system is the
accessible and reliable interface for its users API technology make it more
interesting for the users to interact with the human beings.
3) Cost
effective : This computing techniques greatly reduce the total cost and
capital expenses that comes in arranging the infrastructure .integrated
resources are available at almost no cost to the third party users.
4) Geographical independence of system and
devices: The most exciting feature of the cloud computing is its total
geographical independence. Its users can access the system from the web
browsers anywhere in the world at any time.
5) Multi and large application pool:
Large application pool is available for the users.
6) Reliability: improved design
versions of many redundant website have efficiently increase the performance
and suitability of cloud computing more useful.
7) Security: Security is at the
one level above as compared to the other networks because of the centralization
of data and increased security feature of very individual component.
8) Maintenance: Cloud computing
systems are flexible and easy to maintain because components can be added and
deleted from the infrastructure
