Multi-Region

🟢 Low | Source: AWS What’s New Amazon Cognito now supports multi-Region replication, allowing user pool data — including credentials, configurations, and federation settings — to be synchronised to a standby Region in near real-time. This improves authentication resilience by enabling traffic failover during a regional outage without forcing users to re-authenticate. The feature is available as a paid add-on across most major AWS Regions. Architect’s Take: Review your existing Cognito-based authentication architectures for single-Region dependencies and assess whether the Essentials or Plus tier add-on cost is justified by your RTO/RPO requirements. Ensure your incident response runbooks are updated to include Cognito traffic redirection procedures, and validate that federated identity providers (SAML/OIDC) are accessible from the secondary Region before declaring it ready for failover. ...

🟢 Low | Source: AWS What’s New AWS has added three new execution blocks to Amazon Application Recovery Controller (ARC) Region switch, automating database scaling and failover for Aurora (serverless and provisioned) and Neptune global databases during multi-region failover events. Previously, teams had to manually right-size secondary clusters under incident pressure, adding critical minutes to recovery time. These new blocks remove that manual step, reducing recovery time and human error during regional outages. ...
