Cloud Computing is the latest buzzword in enterprise IT shops around the world—but scratch the surface, and Cloud
Computing consists of a number of existing trends in IT, including virtualization, Software-as-a-Service, utility
computing, and more. Adding to the confusion is a large helping of vendor hype, as both software and hardware vendors push
Cloud Computing as an excuse to buy more gear.
The reality, however, is quite different. Cloud Computing presents a variety
of operational and deployment models that can help enterprises reduce infrastructure costs, provide better customer value,
and position themselves for the future. But organizations won’t succeed with the Cloud unless they understand the
strengths and weaknesses of Cloud Computing and have a carefully planned architectural approach that positions Cloud-based
capabilities in the context of existing IT assets and challenges.
