Users can build dashboards and run queries across domains in the same region without switching endpoints or replicating data. The feature works for both public and VPC-hosted domains, supports IAM and IAM Identity Center authentication, and eliminates the need for costly data pipelines to unify analysis across organizational boundaries. It is available in all AWS regions where OpenSearch UI is supported. ## Full article daily.dev links to this article rather than hosting it.
