Cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a utility over a network. Traditionally organizations stored and maintained data in their own data centers, over which they had complete control. With the emergence of cloud computing organizations can store data in the cloud provider's data centre, but the security of the data in the cloud is a major concern. Data can be stored in the cloud in an encrypted format, but the problem is that while data can be sent to and from a cloud provider's data centre in encrypted form, the servers that power a cloud can't do any work on it that way.
