Cloud computing paradigm is a combination of technology practices and business models working together to deliver agility and scalability to business at a fraction of the cost it would take for traditional IT models to deliver equivalent capabilities.  

Cloud computing refers to any IT capability that can be virtualized, externalized and monetized.  By  virtualizing an IT capability, the underlying technology stake is almost irrelevant to the consumers. By externalizing, the capability is made portable and easy to manage with least number of dependencies. The ability to measure and monitor the service usage at a granular level helps create consumption based charge back model that is most attractive business clients. This way, a business can rent an IT capability without investing heavily in its IT department to stand up this service. Think cash flow!
