Executive Summary

Unlike many technologies, cloud computing has evolved in response to customer needs for better, faster, and cheaper methods of managing information technology. Indeed, individual customer demand defines the level of services, applications, storage, and availability that the cloud delivers. Technology rarely evolves based purely on customer needs, but cloud computing appears to be an exception. Cloud computing has taken on multifaceted definitions as it relates to the many types of IT customers. For the line-of-business executive, cloud computing is a buyer-centric view of technology in which applications are available through purchase, rental, or development. For the chief financial officer, the cloud offers an approach to consume technology in a pay-as-you-go model that delivers the cost benefits of variable pricing without a costly investment in hardware.
