Summary

What is cloud computing? What is driving businesses to use cloud computing? How do IT organizations take advantage of it? Is it safe? What are the usage and pricing models? These are just some of the questions IT organizations have regarding the cloud. This root document "Cloud Computing: Transforming IT" will not only answer these questions, but also serve as the basis for Burton Group's cloud computing coverage by defining the cloud (and associated terms), demonstrating a cloud tiered architecture, examining business and usage models, and describing cloud benefits and pitfalls.
