Beyond the hype, cloud computing does look positioned to truly reshape IT in the years ahead. As reported on eWeek, a new IDC report is projecting that the rise of cloud computing will translate to some $72.9 billion of spending on public IT cloud services in 2015. At that point, IDC says the market for the cloud will account for 46 percent of net growth in IT spending. For now, spending on public IT cloud services is growing at more than four times the rate of the IT market as a whole.

Frank Gens, senior vice president and chief analyst at IDC, even thinks the winners of the "cloud platform wars" will "likely be the new power brokers of the IT industry." The cloud is akin to the mainframe and PC eras, says Gens, who notes that "the new platform promises to radically expand the users and uses of information technology, leading to a wide and entirely new variety of intelligent industry solutions." Ultimately, IDC believes other disruptive technologies like mobile services, wireless networks and social networking will also accelerate cloud adoption.
