Cloud Computing has proven and solved many challenges and also cut

phenomenon. It is going to innovate Education to a further greater
extent, that too at an unimaginable and massive rate. Every
student will be exposed with the tools and the resources which are
locked in at high level scientific and corporate places which are
usually tough to get in touch with, further innovating the pace of
education and expanding its possibilities. Being open in nature,
these resources are free to use and modify, tailor them at no cost,
shape them as per your requirements and let the cloud do all the
hard work.</para>
<para>In data centers today, many computers suffer under-utilization
in computing power and networking bandwidth. For example, projects
may need a large amount of computing capacity to complete a
computation, but no longer need the computing power after
completing the computation. You want cloud computing when you want
a service that's available on-demand with the flexibility to bring
it up or down through automation or with little intervention. Much
like the electrical power we receive each day, cloud computing
provides subscribers or users with access to a shared collection
of computing resources: networks for transfer, servers for
storage, and applications or services for completing tasks.</para>
