AOSREL04-BP04 Employ cross-cluster replication to achieve higher availability
Enhance OpenSearch Service domain availability by employing cross-cluster replication, which replicates user indexes, mappings, and metadata between domains in different AWS accounts or Regions, improving disaster recovery capabilities.
Level of risk exposed if this best practice is not established: Medium
Desired outcome: Your Amazon OpenSearch Service is enabled with cross-cluster replication to enhance domain availability.
Benefits of establishing this best practice:
-
Enhanced domain availability: Employing cross-cluster replication for Amazon OpenSearch Service can enhance domain availability by replicating user indexes, mappings, and metadata from one OpenSearch Service domain to another in another AWS account or Region.
-
Improved disaster recovery: Cross-cluster replication helps with disaster recovery planning by allowing you to replicate data across geographically distant AWS Regions (data centers) and reduce latency in the event of an outage.
Implementation guidance
With cross-cluster replication in Amazon OpenSearch Service, you can replicate user indexes, mappings, and metadata from one OpenSearch Service domain to another domain in another AWS account or AWS Region. If there is an outage, cross-cluster replication assists in disaster recovery and replicates data across geographically distant AWS Regions to reduce latency.
Enabling cross-cluster replication in Amazon OpenSearch Service
involves a multi-step process that includes setting up IAM roles
and configuring both OpenSearch clusters. For a detailed guide on
how to achieve this, see
