CLOUD COMPUTING
Cloud computing is the technology of computing which is totally based
on the internet media. With the help of this ethnology many servers can
offer
softwao.re applications and resources and information to the computer and devices attached on
request with the control of electricity grid. It can be called as the
service architectures or virtualization for improving the utility of the
computational
techniques. Whole 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 services.
How cloud computing works :-
Cloud computing involves the
multiple cloud components that communicate with each other wit
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 take
implementation shape .in year 2007 the most famous organization such as
Google ,IBM and may universities world wide 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 fro 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 come sin 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 any where 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
