This IDC study discusses the use of operating systems through a transition from an in-house captive datacenter to a cloud-based deployment. This study draws on data collected as part of IDC's Server Platform Migration Study, which was conducted earlier in 2012.
"Customers want and expect their investments to be protected, and as they consider a movement to cloud computing, that expectation will remain true," says Al Gillen, program VP, System Software at IDC. "In particular, customers currently using Windows and Linux expect to see those operating systems as the basis for any shared public cloud infrastructure that they use in the future. This, we believe, speaks volumes about the nature of transitions from existing 2nd platform computing solutions over to tomorrow's 3rd platform compute paradigm."
