From the DOD Press Release
The Department of Defense announced today the release of a cloud computing strategy that will move the department’s current network applications from a duplicative, cumbersome, and costly set of application silos to an end state designed to create a more agile, secure, and cost effective service environment that can rapidly respond to changing mission needs. In addition, the Defense Information Systems Agency (DISA) has been named as the enterprise cloud service broker to help maintain mission assurance and information interoperability within this new strategy.
