Virtualization and cloud technology are behind some of the federal data center closures that have put the White House’s data center consolidation initiative ahead of schedule. The Office of Management and Budget says agencies will shut down 178 data centers by the end of this year. Their previous target was 100. Federal CIO Vivek Kundra says governmentwide, they’ll be able to close 378 of the government’s 2,000 data centers by the end of next year. The long term goal is to get rid of 800 centers by 2015.
