OpenSearch UI supports cross-region data access to OpenSearch domains

Amazon Web Services has expanded its OpenSearch Service to support cross-region data access through the OpenSearch UI, allowing users to query and visualize data from OpenSearch domains located across different AWS regions from a single interface. The new capability builds on the cross-account data access feature launched earlier this year, enabling organizations to create dashboards and run analytics across domains distributed across multiple AWS accounts and regions without switching endpoints or replicating data. The feature supports both public and VPC-hosted OpenSearch domains and works with IAM and IAM Identity Center authentication. The cross-region functionality addresses key enterprise challenges around data residency requirements and network efficiency by allowing data to remain in its original location while providing centralized access. Organizations using cross-cluster replication can now directly query both primary and replica domains from a unified interface, simplifying operations for globally distributed search and analytics workloads. The feature is immediately available across all AWS regions where OpenSearch UI is supported, providing enterprises with more flexible options for managing distributed search and observability infrastructure.
