Using AWS GovCloud (US) Regions
If you have used other AWS Regions, you should be aware of specific differences in the AWS GovCloud (US) Regions. For example, Amazon Resource Names (ARNs) and endpoints are different in the AWS GovCloud (US) Regions. For CLI and SDK calls, the Region names are us-gov-west-1 and us-gov-east-1.
In addition to the specific differences, the following topics describe how to maintain compliance with International Traffic in Arms Regulations (ITAR), how to access AWS GovCloud (US), and how to control access to your AWS GovCloud (US) account.
