Primary and replica brokers in Amazon MQ

You can create primary and replica brokers for asynchronous data replication from the primary broker in a primary Amazon Region to the replica broker in a replica Region. The primary Region consists of a redundant pair of active/standby brokers referred to as the primary broker. The secondary Region consists of a redundant pair of active/standby brokers referred to as the replica broker.

The following diagram illustrates a replica broker in a secondary Region receiving asynchronous replicated data from the primary broker in the primary Region.

Primary and replica brokers act as a cross-Region data recovery solution. If the primary broker in the primary Region fails, you can promote the replica broker in the secondary Region to primary by initiating a switchover or failover. The former primary broker then becomes the replica broker, and the former replica broker is promoted to primary broker.
