xCluster deployment

Unidirectional (master-follower) and bidirectional (multi-master) replication

By default, YugabyteDB provides synchronous replication and strong consistency across geo-distributed data centers. However, many use cases do not require synchronous replication or justify the additional complexity and operating costs associated with managing three or more data centers. A cross-cluster (xCluster) deployment provides asynchronous replication across two data centers or cloud regions. Using an xCluster deployment, you can use unidirectional (master-follower) or bidirectional (multi-master) asynchronous replication between two universes (aka data centers).
