Amazon Lex Global Resiliency now supports CloudFormation and existing alias replication

We are excited to announce new capabilities for Amazon Lex Global Resiliency. Building on our existing regional replication framework, we now support existing alias replication and CloudFormation for enabling bot replication. These new features enhance the existing automation that synchronizes your Lex V2 bots, associated resources, versions, and aliases to paired AWS regions in near real-time, while maintaining hot standby resources for immediate failover or an active-active setup.

For contact center customers, this update streamlines disaster recovery by automatically keeping regional configurations in sync. The feature preserves existing alias ARNs during replication and removes the need to update contact flows in multiple places when modifying your bots. With support across the console, CLI, CDK, and CloudFormation, implementing robust disaster recovery solutions is more streamlined than ever.

Global Resiliency for Amazon Lex is available in the following AWS region pairs: us-east-1 (N. Virginia)/us-west-2 (Oregon), and eu-west-2 (London)/eu-central-1 (Frankfurt).

To get started with these new capabilities, contact your Amazon Connect Solutions Architect or Technical Account Manager. Visit the Amazon Lex Global Resiliency documentation to learn more about implementing Global Resiliency for your Lex bots.
