An important feature of cloud computing that was not discussed much during the previous discussion is 'Software as a Service' (SaaS). With SaaS, a company has the ability to rapidly develop and deploy applications without purchasing physical hardware.
Rather, SaaS providers provide the development platform, which is then controlled by a web host provider. Providers can also provide support for the development tools, and can quickly scale up or down the SaaS application when growth demands dictate it. You can contact cloud computing company in India for such kinds of services.
In fact, with modern virtualization technologies such as Xen, VMware, and Hypervisor, a single physical server can be divided among many VDI's, each performing just a small fraction of the work normally needed on each individual physical server.
