Cloud computing is a term that describes a significant change in the way organisations procure, manage and use IT.
It represents a shift away from the concept of building and owning IT as an asset and moving towards a model where applications are hosted by a third party and paid for only when needed.
For a number of years after the term was coined, it remained conceptual, only appearing in the real world as small-pilots. The model has been proven to work now and many organisations are starting to consider it seriously as a method for delivering core business-critical applications into the workplace.
