Amazon Cognito now supports near real-time replication of user pools—including credentials and federation settings—to secondary standby Regions. This facilitates seamless failover by redirecting authentication traffic during regional disruptions without requiring users to reauthenticate.
The feature supports various authentication methods such as username/password and federated identity providers and is available as an add-on in Essentials and Plus tiers across multiple global AWS Regions. While designed to improve system resilience, real-world impact on availability remains to be independently evaluated.
