Cloud computing refers to the provision of computational resources on demand via a computer network. Users or clients can submit a task, such as word processing, to the service provider, without actually possessing the software or hardware. The consumer's computer may contain very little software or data (perhaps a minimal operating system and web browser only), serving as little more than a display terminal connected to the Internet. Since the cloud is the underlying delivery mechanism, cloud based applications and services may support any type of software application or service in use today.



In the past, both data and software had to be stored and processed on or near the computer. The development of Local Area Networks allowed for a system in which multiple CPUs and storage devices may be organized to increase the performance of the entire system. In an extension to that concept, cloud computing fundamentally allows for a functional separation between the resources used and the user's computer, usually residing outside the local network, for example, in a remote data center. Consumers now routinely use data intensive applications driven by cloud technology which were previously unavailable due to cost and deployment complexity.[citation needed] In many companies employees and company departments are bringing a flood of consumer technology into the workplace and this raises legal compliance and security concerns for the corporation.[citation needed]



The term "software as a service" is sometimes used to describe programs offered through "The Cloud".



A common shorthand for a provided cloud computing service (or even an aggregation of all existing cloud services) is "The Cloud".
