June 20, 2011, 4:29 PM — Adoption of cloud computing among end-user companies is moving much more quickly than most analysts anticipated, pushing IT organizations, cloud-computing software vendors and third-party support an integration companies into a frenzy as they try to keep up, according to a new report from IDC.
Part of the impetus for the rapid adoption of cloud is hype from analyst companies such as IDC, which have been predicting rapid growth of the cloud so frequently and consistently that both IT and business-unit managers felt pressured to keep up with the pace of growth in cloud hype and uncomfortable with their lack of control over the pace and the new platform.

Cloud computing is so disruptive a technology, and contains technologies so disruptive, that IT organizations have to migrate much more quickly than they would with other products because so many of the technologies on which they depend have already migrated to the cloud, according to Frank Gens, IDC chief analyst who oversaw the study.
Cloud, mobile computing, wireless networks, big data and social networking "are merging into the industry's third major platform for long-term growth," Gens said in an IDC statement.
The change is at least as big as the shift from mainframes to PCs, but is happening in a much more compressed time period – one in which even a pause in migration is identified as a problem.
Spending on public IT cloud services will grow at more than 27 percent per year during the next five years, rising from $21.5 billion in 2010 to $72.9 billion in 2015, the IDC report said.
By 2015, 46 percent of all new IT spending will be on services in the public cloud.
Three quarters of that will be on SAAS apps, the growth or changes in which will drive increases in spending on storage, server space, networking, application development, systems infrastructure software and other bits of stuff to keep the SAAS apps doing what they're supposed to do and integrate them with legacy apps and data.
