Introduction
The Greek myths tell of creatures plucked from the surface of the Earth and
enshrined as constellations in the night sky. Something similar is happening today in
the world of computing. Data and programs are being swept up from desktop PCs and
corporate server rooms and installed in “the compute cloud”. In general, there is a
shift in the geography of computation.
What is cloud computing exactly? As a beginning here is a definition
“An emerging computer paradigm where data and services
reside in massively scalable data centers in the cloud and
can be accessed from any connected devices over the
internet”
Abstract
Computers have become an indispensable part of life. We need
computers everywhere, be it for work, research or in any such field. As the use
of computers in our day-to-day life increases, the computing resources that we
need also go up. For companies like Google and Microsoft, harnessing the
resources as and when they need it is not a problem. But when it comes to
smaller enterprises, affordability becomes a huge factor. With the huge
infrastructure come problems like machines failure, hard drive crashes,
software bugs, etc. This might be a big headache for such a community. Cloud
Computing offers a solution to this situation.
Cloud Computing
A definition for cloud computing can be given as an emerging computer
paradigm where data and services reside in massively scalable data centers in the
cloud and can be accessed from any connected devices over the internet.
Cloud computing is a way of providing various services on virtual machines
allocated on top of a large physical machine pool which resides in the cloud. Cloud
computing comes into focus only when we think about what IT has always wanted - a
way to increase capacity or add different capabilities to the current setting on the fly
without investing in new infrastructure, training new personnel or licensing new
software. Here ‘on the fly’ and ‘without investing or training’ becomes the keywords
in the current situation. But cloud computing offers a better solution.
