Re: To be honest ...
Would you care to explain how the Cloud Act 2018 applies to GovCloud hosting? Whether it is in AWS or Azure, GovCloud appears to be completely outside of this act.
You're likely equating GovCloud facilities with public cloud when they are separate facilities (physical/location/operational/etc) covered by strict federal requirements. Requirements that Microsoft hasn't quite reached yet... Requirements Google has only recently agreed to meet necessary GovCloud requirements after previously withdrawing from JEDI. As Oracle/IBM have yet to build facilities for their proposed JEDI bids it was safe to assume they would be compliant in 2-3 years time.
Meanwhile, AWS has been compliant with the necessary requirements for ~3 years when they came into existence. Still...clearly Microsoft will be a better fit. When it eventually completes its resilient facilities.
