Amazon's cloud computing service, AWS, has more than five times the combined capacity of its next 14 rivals, according to a research report by Gartner, as cited in The Seattle Times' recent look at Amazon's efforts to win the contract for the CIA's cloud services.

Current analyst estimates of AWS annual revenue: $3 billion.

CIA contract that AWS just won: $600 million.

Meanwhile, IBM just won $1 billion: 

ARMONK, N.Y. - 14 Aug 2013: IBM (NYSE: IBM) today announced it will work with the United States Department of the Interior (US DOI) as the Department embarks on a decade long transformation of their information technology (IT) systems to a cloud computing model. As part of an indefinite delivery/indefinite quantity (IDIQ) contract, valued for IBM up to $1 billion, the Department may use IBM cloud computing technologies, services and hosting as the foundation of their next generation infrastructure.

That's crazy. Why use different, incompatible clouds?

Could it be a spook thing?

Maybe. It seems crazy they're not running their own clouds.

OpenStack, people. It's a good idea.
