Amazon MQ Broker Architecture

Amazon MQ brokers can be created as single-instance brokers or active/standby brokers. For both deployment modes, Amazon MQ provides high durability by storing its data redundantly, across multiple Availability Zones (multi-AZs) within an AWS Region. Amazon MQ ensures high availability by providing failover to a standby instance in a second Availability Zone.

Note

Amazon MQ uses Apache KahaDB as its data store. Other data stores, such as JDBC and LevelDB, aren't supported.
