I remember a few years back that there were many law enforcement agencies who did not want to move to the cloud due to security issues. Now, you have the Defense Department moving lock, stock and barrel into the cloud. I read several articles on the decision to go with Microsoft rather than Amazon Web Services (AWS), which many assumed would get the contract.
It is also assumed that AWS will challenge the awarding of the contract. In fiscal 2018, the Government Accountability Office received 2,400 contract protests. Of those, 92 were won by the protester. The success rate doesn't look that good.
However, there were other big successes, for instance, the United States Air Force contract for the new airborne refueling tanker went to Airbus. Boeing challenged and now they are building new tankers on the Boeing 167 airliner body.
