Abstract :
Cloud computing has
gained a lot of hype in the current world of I.T. Cloud computing is said to be
the next big thing in the computer world after the internet.
In general terms the
Cloud computing is referred to as anything that uses internet and computing is
done at some remote location and the result are displayed on the user screen
and the user access the cloud using the familiar web browser. This definition
is true to some extent however not completely.
Cloud computing is a
broad, new technology and young as of now. The industry still struggles to
define as to what to call as Cloud computing and what not to.
Like any new IT trend, cloud
computing gets its fair share of hype, and with it comes a multitude of vendors
that use the term in ways it was never intended for, making it devoid of any
sense. When pushed to the extreme, a simple server connected to a network seems
to qualify as a cloud, allowing pundits to mock the concept. Yet cloud
computing is not a passing fad. It is a major step forward in the development
of distributed computing, and one that will reshape the IT industry. But for it
to happen, we must agree on a clear definition of the concept first, and the
less technical it is, the better.
Cloud
computing requires a dynamic computing infrastructure. The foundation for the
dynamic infrastructure is a standardized, scalable, and secure physical
infrastructure. There should be levels of redundancy to ensure high levels of
availability, but mostly it must be easy to extend as usage growth demands it,
without requiring architecture rework. Next, it must be virtualized.
