Cloud Computing
Definition
From the Wikipedia [1]:
"Cloud computing is a computing paradigm shift where computing is moved away from personal computers or an individual server to a “cloud” of computers. Users of the cloud only need to be concerned with the computing service being asked for, as the underlying details of how it’s achieved are hidden. This method of distributed computing is done through pooling all computer resources together and being managed by software rather than a human." (http://en.wikipedia.org/wiki/Cloud_computing)
