Cloud computing's on-demand, pay-as-you-go service model is transforming IT from massive, cumbersome, internal cost centers into agile, reactive, external services that are used not merely as business tools, but as the medium by which business is conducted. Unfortunately, marketing hype, unclear return on investment, and difficult risk/benefit analysis continue to hinder cloud adoption. Organizations that best understand cloud computing can take advantage of its strengths and mitigate its risks. In this management initiative, Gartner clarifies the discussion by defining cloud computing and its characteristics, architectural model, benefits, and shortcomings.
