Cloud computing is becoming established, and enterprises around the world are beginning to deploy diverse workloads to public and private clouds, gaining benefits not only in cost savings but also in increased scalability and agility. Our 2009 Study Tour was designed to help delegates explore the issues and advantages of the cloud for their own organizations by visiting some of the leading providers and early adopters of cloud computing. This report summarizes what we heard on the tour, and the lessons delegates took away to guide their organizations' steps into the cloud.
