AWS IAM Identity Center now supports multi-Region replication for AWS account access and application use

Summary

The AWS IAM Identity Center has introduced multi-Region replication capabilities, allowing organizations to replicate workforce identities and permission sets across multiple AWS Regions. This enhancement aims to improve resiliency and performance for AWS account access and managed applications. Users can configure IAM Identity Center to connect with external identity providers like Microsoft Entra ID and Okta, enabling seamless access even during service disruptions in the primary Region. The article outlines the steps necessary to enable this feature, including the replication of AWS Key Management Service (KMS) keys and the management of IAM Identity Center configurations from the primary Region. It also highlights key considerations and operational limitations when using IAM Identity Center across multiple Regions.
