What is Cloud Computing? Massive computing resources , deployed among virtual datacenters, dynamically allocated to specific users and tasks and accessed as a service via an user interface (UI), such as a web browser . The physical cloud resources may reside in a number of locations, the details of which are not typically known to the service’s users. Cloud resources are offered as a service on an as needed basis. The cloud itself typically consists of large numbers of commodity-grade servers, harnessed to deliver highly scalable and reliable on-demand services.
