OpenSearch UI supports Cross Account Data Access to OpenSearch domains

Amazon OpenSearch Service now supports cross-account data access, enabling users to access OpenSearch domains hosted in different AWS accounts from within a single OpenSearch UI application. With this feature, you can query or build dashboard with data from OpenSearch domains across different accounts in the same region - without switching to a new endpoint or replicating data. Cross-account data access is available for OpenSearch domains hosted in both public and Virtual Private Cloud (VPC) configurations.

With cross-account data access, teams no longer need to consolidate data into a single account or maintain costly data pipelines to enable unified analysis across organizational boundaries. This makes it easier to build centralized observability, search, and security analytics workflows that span multiple AWS accounts while keeping data in place and maintaining each account's access controls. Cross-account data access supports both IAM (including SAML via IAM federation) and IAM Identity Center (IdC) for end user authentication.

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