Deploy AWS applications and access AWS accounts across multiple Regions with IAM Identity Center

This article explains how to deploy AWS applications and access AWS accounts across multiple Regions using IAM Identity Center multi-Region replication for improved resilience and reduced latency.

• Multi-Region replication enables active access portals in additional Regions with automatic failover capabilities
• Requires multi-Region customer-managed KMS keys for encryption of identity data
• Primary Region maintains centralized control; additional Regions provide read-only replicas
• Identity provider configuration must be updated with new Regional ACS URLs and bookmark applications
• AWS managed applications can be deployed in additional Regions for Region-local access
• AWS CLI supports multiple Regional profiles for seamless Region switching during disruptions
• Permission set assignments automatically replicate to additional Regions
• Optional automatic failover using Route 53, Application Recovery Controller, and ALB

Multi-Region Identity Center replication provides organizations with resilient, low-latency access to AWS resources while maintaining centralized identity management from the primary Region.
