Juniper Networks sponsored and released a survey of 200 federal IT executives conducted by MeriTalk. Only 10 percent of the executives surveyed felt the federal government would meet its lofty expectations, while 23 percent believe the government will end up with more data centers.
The reasoning behind the executives' predictions comes down to two factors: complexity and demand. The complexity comes from app-driven infrastructure and reliance on legacy applications. Legacy apps, unless rewritten, make it more difficult to consolidate operations, GigaOM reports. Despite offloading some demand to the cloud, a number of applications, for security or technological reasons, won't be able to run in the public cloud.
However, despite the lack of optimism from federal CIOs, the elimination of some energy costs is already occurring to some degree. According to Stanford professor Jonathan Koomey, the rate of growth of energy consumption by data centers has grown slower than the EPA predicted in 2007, largely in part to the recession and improved efficiency in data centers.
