AWS Secrets Manager now enables you to replicate secrets across multiple AWS Regions. You can now give your multi-Region applications access to replicated secrets in the corresponding Regions and rely on AWS Secrets Manager to keep the replicas in sync with the primary secret. In scenarios such as disaster recovery, you can read replicated secrets from your recovery Region, even if your Primary Region is unavailable. You can use this functionality through the AWS Secrets Manager console, CreateSecret and ReplicateSecretToRegions API, or via AWS CloudFormation to replicate secrets in one or more Regions.
