After all, at a massive scale, having access to industry standard tools for provisionning makes sense: give $$$ to AMZN for their software stack and hw integration cost probably less than building your own...?
A really private AV zone is just a step away: put gov guards at the entrance of DCs, replace all AWS teams by in-house personnel (or have AWS teams sworned in at the relevant level...?)
"a $600 million computing cloud developed by Amazon Web Services for the Central Intelligence Agency over the past year will begin servicing all 17 agencies that make up the intelligence community."
