AWS IAM Identity Center Now Spreads Across More Regions
AWS IAM Identity Center just got multi-Region replication support in opt-in Regions, plus GovCloud and China—meaning your identity data automatically syncs across regions for better resilience. If your primary Region goes down, users keep their access through already-provisioned entitlements elsewhere, and you can deploy apps regionally while managing identities from one place.
