Broker - Amazon MQ


A broker is a message broker environment running on Amazon MQ. It is the basic building block of Amazon MQ. The combined description of the broker instance class (m5, t3) and size (large, micro) is a broker instance type (for example, mq.m5.large). For more information, see Broker instance types.

  • A single-instance broker is comprised of one broker in one Availability Zone behind a Network Load Balancer (NLB). The broker communicates with your application and with Amazon Elastic Block Store (EBS). Single-instance brokers provide high throughput and lower latency.

  • A cluster deployment is a logical grouping of three RabbitMQ broker nodes behind a Network Load Balancer, each sharing users, queues, and a distributed state across multiple Availability Zones (AZ).

For more information, see Broker architecture.

You can enable automatic minor version upgrades to new minor versions of the broker engine, as new versions of the RabbitMQ engine are released. Automatic upgrades occur during the maintenance window defined by the day of the week, the time of day (in 24-hour format), and the time zone (UTC by default).

Supported protocols

You can access your RabbitMQ brokers by using any programming language that RabbitMQ supports and by enabling TLS for the following protocols:

Listener ports

Amazon MQ managed RabbitMQ brokers support the following listener ports for application-level connectivity via amqps, as well as client connections using the RabbitMQ web console and the management API.

  • Listener port 5671 - Used for connections made via the secure AMQP URL. For example, given a broker with broker ID b-c8352341-ec91-4a78-ad9c-a43f23d325bb, deployed in the us-west-2 region, the following is the broker's full amqp URL:

  • Listener ports 443 and 15671 - Both listener ports can be used interchangably to access a broker via the RabbitMQ web console or the mangement API.


A RabbitMQ broker has several attributes:

  • A name. For example, MyBroker.

  • An ID. For example, b-1234a5b6-78cd-901e-2fgh-3i45j6k178l9.

  • An Amazon Resource Name (ARN). For example, arn:aws:mq:us-east-2:123456789012:broker:MyBroker:b-1234a5b6-78cd-901e-2fgh-3i45j6k178l9.

  • A RabbitMQ web console URL. For example,

    For more information, see RabbitMQ web console in the RabbitMQ documentation.

  • A secure AMQP endpoint. For example, amqps://
