Good question. And the IT industry still hasn’t agreed on a single definition. Gartner defines Cloud Computing as “a style of computing in which scalable and elastic IT-enabled capabilities are delivered as a service using Internet technologies.” Other organisations see it as a method to fully utilise all available computing resources even when those resources are located hundreds of miles from each other (often called federated systems). Whatever it is, Cloud Computing is changing the way users interact with applications, services, and infrastructure, and how services are delivered.
