OpenSearch UI supports cross-region data access to OpenSearch domains

Amazon OpenSearch Service Updates

Amazon OpenSearch Service now supports cross-region data access for OpenSearch UI, allowing users to access OpenSearch domains hosted in different AWS Regions from a single OpenSearch UI application. This feature, combined with cross-account data access, enables querying or building dashboards on OpenSearch domains in various accounts and Regions without switching endpoints or replicating data. Cross-region data access is available for OpenSearch domains in both public and Virtual Private Cloud (VPC) configurations.

With this update, teams can build centralized analytics, search, and observability workflows across globally distributed deployments while keeping data in place, meeting data residency requirements, minimizing inter-region egress, and preserving each Region’s latency and availability characteristics. If using cross-cluster replication, you can now query both primary and replica domains directly from a single OpenSearch UI application. Cross-region data access supports both IAM and IAM Identity Center for end-user authentication.

Cross-region data access to OpenSearch domains is available in all AWS Regions where OpenSearch UI is available. For more information, see Cross-region data access to OpenSearch domains in the Amazon OpenSearch Service Developer Guide.
