The new feature lets users access OpenSearch domains across different AWS accounts from a unified OpenSearch UI application, streamlining workflows that require data aggregation from multiple organizational units. It supports domains in both public and VPC configurations within the same region, maintaining existing access controls.
This capability eliminates the need to consolidate data or maintain complex pipelines, simplifying centralized observability, search, and security analytics. Authentication supports both IAM and IAM Identity Center, facilitating secure cross-account query operations without endpoint switching.
