Twenty five large federal agencies have identified 78 services suitable for migration to the cloud, according to a document released May 25 by the Office of Management and Budget.

The most common application, according to a FierceGovernmentIT tabulation, is email, with 14 agencies having decided to choose a cloud version. In a close second is website hosting, with 10 agencies having named it as a cloud-suitable function. (Scroll down for a graph of all 78 services.)

At a May 25 hearing of the Senate Homeland Security, Vivek Kundra, the administrator for e-government and information technology--who also goes by the title of federal chief information officer--said a move to cloud computing by federal agencies should cause $5 billion in cost savings.

"Now, a lot of this will be a function of the procurements that are going to be put out and the competitive nature of those procurements, but we expect to save $5 billion through that process," Kundra said.

Kundra also projected savings of $3 billion to be had through an ongoing data center consolidation project.

During the hearing, Kundra also announced a change to the practice of enterprise architecture within the federal government.

"We're repurposing the architectural community to find and eliminate duplication and move agencies to shared services," he said, criticizing previous enterprise architecture efforts as "an aimless paperwork exercise, churning out artifact after artifact that serve only to fill metal cabinets across Washington."
