Oh please... more of this JEDI/WaPo stuff? It ignores that the NSA (and by extension, the DOD) have a long relationship with Microsoft just as the CIA have a long relationship with Amazon and have "AWS-lite" installed at Langley. Microsoft has been very accommodating to the DOD, agreeing to continue maintenance on Windows XP for as long as the Navy continues to request (and pay for) it. Yes, Trump has his gripes with WaPo and might have suggested to Mattis to screw AWS, but it's very likely that the Five Sided Puzzle Palace wanted to go with Azure Stack all along but had to do the open competition thing to avoid being sued by companies not named Microsoft.
