Cloud computing is the latest effort in delivering computing resources as a service. It represents a shift away from computing as a product that is purchased, to computing as a service that is delivered to consumers over the internet from large-scale data centers - or "Clouds". Cloud computing has been mentioned for just under two years in relation to services or infrastructural resources, which can be contracted over a network. Thus, the idea of renting instead of buying IT is nothing new.
