Amazon is continuing to fight the Department of Defense over a $10 billion contract, as the Pentagon has completed its review of the deal and determined once again that it was correct to award the entire project to Microsoft.

The DOD launched bidding for the Joint Enterprise Defense Infrastructure (JEDI) project, a massive cloud-computing contract, in 2019. By April of that year, the shortlist was down to two finalists: Amazon AWS and Microsoft Azure. Amazon was widely considered the favorite, and many industry watchers expressed surprise when Microsoft ultimately landed the deal in October 2019.
