CLOUD COMPUTING
1. Introduction
The process and
possibilities of business has been radically affected and hugely expanded by
continuously changing technological advances. For instance, the invention of
printing press and the consequent ability to produce books in large numbers
created new business of publishing. This in turn helped in organizing education
and determined the structure of university. The invention of steam engine led
to creation of transportation industry and the invention of aero plane created
aviation industry and computers created industry of information. Something
similar is ushering in the field of computing. Cloud computing is a
business model that harnesses the web as the ultimate business platform. Cloud
computing is impregnated with immense potential for array of practical
applications. The model is expected make computing needs available via web on
retail basis and is called cloud computing. Cloud computing intends to make the
Internet the ultimate home of all computing resources- storage, computations,
applications and allow end user to available them in quantities of her choice,
location of their preferences, for duration of their liking. In other world web
become the provision store for all your computing needs.

What is CLOUD COMPUTING?
Why do I buy a computer
when I use it for only few hours a week? Why do I buy a printer when I
need printing occasionally? Is it possible to avail computing on “need basis”
as it is possible in case of “electricity” or “water? In other words, can I
avail computing resources such as storage, application, and infrastructure as a
“utility”?
The answer is yes. And
the name of model which is expected make computing available on retail
basis is called cloud computing. Cloud computing intends to make the
Internet the ultimate home of all computing resources- storage, computations,
applications and allow end user (both individuals and business) to avail these
resources in quantities of her choice, location of their preferences, for
duration of their liking. In other world web become the provision store for all
your computing needs. A business model built on this paradigm offers these
resources as services either on pay per use basis or rental basis.
Cloud computing is
a term used to describe both a platform and type of application. A cloud
computing platform dynamically provisions, configures, reconfigures, and
deprovisions servers as needed. Servers in the cloud can be physical machines
or virtual machines. Advanced clouds typically include other computing
resources such as storage area networks (SANs), network equipment, firewall and
other security devices.

Why cloud computing?
Cloud computing
infrastructure accelerates and fosters the adoption of innovations. Cloud
computing can enable innovations. It alleviates the need of innovators to find
resources to develop, test, and make their innovations available to the user
community. Innovators are free to focus on the innovation rather than the
logistics of finding and managing resources that enable the innovation. Cloud
computing helps leverage innovation as early as possible to deliver business
value to a company and its customers.
Cloud computing
infrastructure allows enterprises to achieve more efficient use of their IT
hardware and software investments. Cloud computing can increase profitability
by improving resource utilization. Pooling resources into large clouds drives
down costs and increases utilization by delivering resources only for as long
as those resources are needed. Cloud computing allows individuals, teams, and
organizations to streamline procurement processes and eliminate the need to
duplicate certain computer administrative skills related to setup,
configuration, and support.
