Deploy AWS Applications and Access Accounts Across Regions
🔁 AWS now supports IAM Identity Center multi-Region replication, enabling workforce access and supported AWS managed applications to operate from additional Regions for improved resiliency and lower latency. Administrators create a multi-Region customer-managed KMS key, replicate it to target Regions, and add those Regions in the Identity Center console. External IdP configurations (for example, Okta or Microsoft Entra ID) must be updated with new ACS and access portal URLs so both service-provider and IdP-initiated flows work. Instance-level management remains centralized in the primary Region while additional Regions provide read-only replicated configuration and local application access.
