Wikipedia defined Cloude computing as: *Cloud computing* is Internet <http://en.wikipedia.org/wiki/Internet>("cloud") based development and use of computer technology ("computing"). [1] <http://en.wikipedia.org/wiki/Cloud_computing#cite_note-0>[2]<http://en.wikipedia.org/wiki/Cloud_computing#cite_note-1> [3] <http://en.wikipedia.org/wiki/Cloud_computing#cite_note-2> It is a style of computing in which dynamically scalable<http://en.wikipedia.org/wiki/Scalability>and often virtualised <http://en.wikipedia.org/wiki/Virtualisation> resources are provided as a service <http://en.wikipedia.org/wiki/Everything_as_a_service>over the Internet. [4] <http://en.wikipedia.org/wiki/Cloud_computing#cite_note-really-3>[5]<http://en.wikipedia.org/wiki/Cloud_computing#cite_note-4> [6] <http://en.wikipedia.org/wiki/Cloud_computing#cite_note-5>[7]<http://en.wikipedia.org/wiki/Cloud_computing#cite_note-6>Users need not have knowledge of, expertise in, or control over the technology infrastructure "in the cloud" that supports them[8]<http://en.wikipedia.org/wiki/Cloud_computing#cite_note-7>
The concept incorporates infrastructure as a service<http://en.wikipedia.org/wiki/Infrastructure_as_a_service>(IaaS), platform as a service <http://en.wikipedia.org/wiki/Platform_as_a_service> (PaaS) and software as a service <http://en.wikipedia.org/wiki/Software_as_a_service>(SaaS) as well as Web 2.0 <http://en.wikipedia.org/wiki/Web_2.0> and other recent (ca. 2007–2009)[ 9] <http://en.wikipedia.org/wiki/Cloud_computing#cite_note-JWilliams-8>[10]<http://en.wikipedia.org/wiki/Cloud_computing#cite_note-ACampbell-9>technology trends which have the common theme of reliance on the Internet for satisfying the computing needs of the users. Examples of SaaS vendors include Salesforce.com <http://en.wikipedia.org/wiki/Salesforce.com> and Google Apps <http://en.wikipedia.org/wiki/Google_Apps> which provide common business applications online that are accessed from a web browser<http://en.wikipedia.org/wiki/Web_browser>, while the software <http://en.wikipedia.org/wiki/Software> and data<http://en.wikipedia.org/wiki/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<http://en.wikipedia.org/wiki/Computer_network_diagram>, and is an abstraction for the complex infrastructure it conceals.<http://en.wikipedia.org/wiki/Cloud_computing#cite_note-The_Internet_Cloud-10> All the best Ashraf Galal On Tue, Mar 17, 2009 at 10:15 AM, <[email protected]> wrote: > I think you may want to do more reading on Cloud computing and federated > enterprise before mack such statements.
