US regions, residency and public sector clouds
Every major provider runs several US regions, such as AWS us-east-1 and us-west-2, Azure East US and West US 2 and Google Cloud us-central1, so production data can stay in the US with a disaster recovery copy in a second region. Region choice affects latency, price and which services are available, so we confirm the services you need exist in your chosen regions before committing.
Federal agencies buy cloud services through FedRAMP, and defense contractors handling controlled unclassified information work toward NIST SP 800-171 and CMMC requirements. These can require AWS GovCloud (US) or Azure Government and restrict who may administer the environment, which can rule out offshore administrators. When a contract's personnel rules mean the work must stay with a US team, we tell you plainly.
