The federal government is closing nearly 800 of its 2000 data centers in the next four years, according to the New York Times. Over four years, the government will swap its sprawl of data centers in favor of cloud computing technology.

The federal CIO, Vivek Kundra, says “Tapping cloud computing services could save the government an additional $5 billion a year, reducing the need for individual government agencies to buy their own software and hardware.” By switching to a cloud-based email solution alone, the General Services Administration and Department of Agriculture have saved $42 million.
