Cloud Computing is the term which has been attached to what is now generally regarded as the next stage in the Internet’s development: the renting or borrowing of software online by users rather than buying and installing it on their computers. As a business model it is pretty much the same as, say, Yahoo mail services, but takes the concept a lot further. The Internet “Cloud” would enable whole businesses to access a centralized hub to run their software tools, processing and storage, as online rented facilities. The way technology is used to service customers, suppliers, and partners would be totally different and already some companies like Amazon and Google have substantial IT resources in the cloud. They report that many of the constraining issues of, for example, cost, capacity, time and power, associated with the present Internet environment have been either substantially reduced, or eliminated.
