For certain type of specific tasks, the authors may require some specialized resources (H/W and S/W), which may be very costly. So every customer/client cannot afford the price of the computation. This problem gave birth to the cloud computing. In this technology such type of resources are placed on the server. Any client can utilize that resources on demand basis, and charged by the service provider for utilizing their resources. The cloud computing refers to a infrastructure (model), in which all the overhead of computation and required specific hardware and software are moved to the server side from the client side.
