Previously requiring manual creation of customer managed KMS keys, policy configuration, and regional additions, the new multi-Region instance option automatically creates the required KMS key and replicates the instance to another region. This enhances resilience by maintaining user access to AWS accounts despite regional disruptions in IAM Identity Center.
Customers selecting this option benefit from streamlined deployment with options for single-Region, multi-Region, or custom instance configuration. Multi-Region support is available in 17 default commercial AWS Regions, with KMS charges applying for the managed keys. IAM Identity Center usage itself remains free of additional fees.
