RabbitMQ

Deploy RabbitMQ on Out Plane — the most widely deployed open-source message broker, supporting AMQP 0-9-1, AMQP 1.0, MQTT, and STOMP protocols. RabbitMQ enables reliable asynchronous communication between microservices with message persistence, acknowledgments, flexible routing through exchanges, and dead-letter queues for error handling.

RabbitMQ includes a management UI for monitoring queues, exchanges, connections, and message rates. It supports clustering for high availability, shovel and federation plugins for cross-datacenter messaging, and priority queues for workload prioritization. Out Plane handles provisioning and networking.

Ideal for microservices architectures, distributed task queues, event-driven systems, background job processing, and any application that needs reliable asynchronous communication between services.
