Gartner, Inc. “Hype Cycle for Cloud Computing,” 2009, by Daryl Plummer et al, July 16, 2009.
“A standardized IT capability, such as SOFTWARE, APP PLATFORM, OR INFRASTRUCTURE, delivered via Internet technologies in a pay-per-use and self-service way. “
“How To Message "Cloud" Offerings And Not Get Lost In The Fog,” Forrester Research, Inc., July 2009.
