Distributed Message Service (DMS) for RocketMQ is message-oriented middleware that delivers low latency, high flexibility, high throughput, dynamic expansion, easy management, and abundant messaging functions. Users can purchase RocketMQ instances. Producer clients can access RocketMQ instances for message production. The produced messages are stored in topics of RocketMQ instances. Consumer clients can subscribe to topics to consume messages.

The following figure shows the process of using a RocketMQ instance to produce and consume messages.
