Amazon OpenSearch Service expanded OpenSearch UI capabilities to access data across OpenSearch domains hosted in different AWS Regions and accounts. This cross-region data access facilitates centralized analytics, search, and observability workflows without needing data replication or endpoint switching. The functionality supports both publicly accessible and VPC-hosted OpenSearch domains, preserving data residency and reducing latency.
This improvement complements earlier cross-account data access, allowing flexible domain combinations. Users can create dashboards and queries combining primary and replica domains managed via cross-cluster replication. Authentication supports IAM and IAM Identity Center. The feature is broadly available in all regions where OpenSearch UI operates, enabling teams globally to streamline multi-domain data analysis.
