  Cloud computing is the next generation computing. Adopting the cloud
computing is like signing up new form of a website. The GUI which controls the
cloud computing make is directly control the hardware resource and your
application. The difficulty part in cloud computing is to deploy in real
environment. Its' difficult to know the exact cost and it's requirement until
and unless we buy the service not only that whether it will support the
existing application which is available on traditional data center or had to
design a new application for the cloud computing environment. The security
issue, latency, fault tolerance are some parameter which we need to keen care
before deploying, all this we only know after deploying but by using simulation
we can do the experiment before deploying it to real environment. By simulation
we can understand the real environment of cloud computing and then after it
successful result we can start deploying your application in cloud computing
environment. By using the simulator it will save us lots of time and money.
