Large enterprises are prioritising private clouds, according to a survey by analyst Forrester Research. The survey of 2,321 IT executives reported that 60% of those prioritising private clouds as a high or critical priority were enterprises with more than 1,000 employees. Forrester principal analyst James Staten said, "Larger companies sink more investment into their own data centres, operations personnel, and IT processes. Thus, they have more to lose if the business goes to the public clouds. These organisations also have more in-house capabilities with which to build and operate a private cloud."
Staten said that many IT departments were under great pressure to stand up a private cloud as an alternative platform to the public clouds which claim higher levels of efficiency and lower costs due to their massive scale. "We found that respondents planning, implementing, or expanding their application footprint on public cloud infrastructure-as-a-service (IaaS) platforms grew from just 13% in 2009 to 21% this year," he explained.
However, the use of server virtualisation did not play a significant factor in determining whether an organisation was more likely to prioritise a private cloud. Staten said, "Of those prioritising a private cloud, 64% were expanding or upgrading their server virtualisation implementation - versus just 56% when respondents don't prioritise private cloud. These numbers drop precipitously to 11% and 14%, respectively, for companies that aren't expanding server virtualisation."
