Amazon OpenSearch Service now supports cross-cluster replication on existing domains. Cross-cluster replication enables you to automate copying and synchronizing of indices from one domain to another at low latency in same or different Amazon Web Services accounts or Regions. With cross-cluster replication, you can achieve high availability for your mission critical applications with sequential data consistency.

Previously, you had to create a new domain to use cross-cluster replication. With this release, you can continue to use your existing domains to take advantage of cross-cluster replication. Cross-cluster connections lets customers set up a secure connection between domains. With cross-cluster replication for Amazon OpenSearch Service, you can replicate indices at low latency from one domain to another in same or different Amazon Web Services Regions without needing additional technologies. You can continuously monitor the replication status via APIs. Additionally, if you have indices that follow an index pattern, you can create automatic follow rules and they will be automatically replicated.

Cross-cluster replication is now available for Amazon OpenSearch Service domains in the Amazon Web Services China (Beijing) Region, operated by Sinnet, and the Amazon Web Services China (Ningxia) Region, operated by NWCD.
