AWS Identity and Access Management (IAM) Roles Anywhere is now available in the AWS GovCloud (US-East) and AWS GovCloud (US-West) Regions. IAM Roles Anywhere enables workloads that run outside of AWS to access AWS resources using IAM roles and policies in the same way you do from your AWS workloads. IAM Roles Anywhere allows your workloads such as servers, containers, and applications to use X.509 digital certificates to obtain temporary AWS credentials.
