Amazon OpenSearch Service now supports cross-cluster replication on existing domains. Cross-cluster replication enables you to automatically copy and synchronize indexes from one domain to another at low latency in same or different AWS 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 now enable cross-cluster replication on your existing domain. Cross-cluster connections help customers set up a secure connection between domains. With cross-cluster replication for Amazon OpenSearch Service, you can replicate indexes at low latency from one domain to another without needing additional technologies. You can continuously monitor the replication status via APIs. Additionally, if you have indexes that follow an index pattern, you can create rules to automatically replicate them.

Cross-cluster replication is available for Amazon OpenSearch Service across 26 regions globally. Please refer to the AWS Region Table for more information about Amazon OpenSearch Service availability. To learn more about cross-cluster replication, please see the documentation.
