(Source: Wikipedia) Cloud computing refers to the use of Internet ("cloud") based computer technology for a variety of services. It is a style of computing in which dynamically scalable and often virtualised resources are provided as a service over the Internet. Users need not have knowledge of, expertise in, or control over the technology infrastructure "in the cloud" that supports them.

The cloud is a metaphor for the Internet, based on how it is depicted in computer network diagrams, and is an abstraction for the complex infrastructure it conceals.

Cloud lock-in refers to the degree of difficulty associated with moving an application from one cloud provider to anywhere else – whether to another provider or back to your own data center. Cost, time, level of effort, and portability of data are the major sources of cloud lock-in. AppZero busts cloud lock-in with applications and data that are 100% portable.
