What is cloud technology?

Answer: Cloud computing 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 concept incorporates infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS) as well as Web 2.0 and other recent (ca. 2007-2009) technology trends that have the common theme of reliance on the Internet for satisfying the computing needs of the users. Examples include salesforce.com and Google Apps which provide common business applications online that are accessed from a web browser, while the software and data are stored on the servers.

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

Cloud technology provides the ability to save files or run applications for external host servers. It can connect computers over a network and has the ability to run a program on many connected computers at the same time.

Google is an example of cloud computing with the use of Gmail and its 'Drive' which consists of 'Google Docs' and forms, that can invite other connected computers to your work and together create a 'live' project.
