Five companies have been awarded a multibillion-dollar cloud computing contract by the Central Intelligence Agency.

The CIA has awarded its Commercial Cloud Enterprise (C2E) contract to AWS, Microsoft, Google, IBM and Oracle. The goal of the contract to provide “foundational cloud services, including infrastructure-, platform- and software-as-a-service capabilities, as well as professional services,” according to Nextgov.

As Nextgov points out, awarding the contract to multiple firms opens the way for multiple companies to serve the intelligence community in mission-critical ways. At the time, AWS has the highest clearance levels, with Microsoft coming in at second place. As the other companies continue working on the contract however, it stands to reason they will eventually qualify for top-secret clearances as well.

The contract award is also a big win for IBM and Oracle, both of whom are working to establish themselves as top competitors to the Big Three.
