There’s a huge difference between having your primary business being services projects basically as an extension of the government and your revenue center being unrelated private sector funding. Your corporate structure and business incentives are completely different as a result. I know Lockheed spend many millions of dollars trying to build a DoD-centric IaaS as AWS was being built and it didn’t really matter in the end because so many projects are going to GovCloud. Sure, lots of TS projects are not ever going to be in AWS but boy are people trying. VMware was bought before to try to contain the sheer sprawl of configuration in the Pentagon (your cost is almost entirely around organizational complexities rather than compute / storage cost due to being so heavy on labor costs in most enterprise orgs so the math is fuzzier but usually results in layoffs / workforce optimizations if successful).
