Cloud computing is an upcoming paradigm which provides ubiquitous, scalable and resilient resources to users according to pay as you go model. The resources such as networking devices, storage devices, computational devices (CPU) etc. present in Cloud are provided to users in the form of virtual machines. Physical resources at the backend are used to configure virtual machines as per requirements of the users. This concept of virtualization used in Cloud helps to provide a vibe of security to users who think that the resources are fully dedicated to them but actually they all are sharing the same backend resources present in Cloud. Same service of a cloud could be implemented at different geographical locations which provides fault tolerance. Moreover, users can avail services of cloud anywhere at any time (provided they are connected to network) which shows ubiquitous nature of services implemented in Cloud.
