Cloud Computing JournalIf cloud, in its many forms, gains traction -- like any other big change affecting business and IT -- adopters require a lot of rationales, incentives, and measurable returns to keep progressing successfully. But, just as the definition of cloud computing itself can elicit myriad responses, the same is true for why an organization should encourage cloud computing. The major paybacks are not clearly agreed upon, for sure. Are the paybacks purely in economic terms? Is cloud a route to IT efficiency primarily? Are the business agility benefits paramount? Or, does cloud transform business and markets in ways not yet fully understood? We seek a list of the top reasons why exploiting cloud computing models make sense, and why at least experimenting with cloud should be done sooner rather than later. We have assembled a panel of cloud experts to put some serious wood behind the arrow leading to the cloud.
