A consumer is the client that calls the DMS API to receive messages from queues. The messages that are confirmed to be consumed will be deleted from the queue. Consumers in the same consumer group can concurrently consume different messages from one queue.
Consumer groups distinguish the consumer clients. The messages in one queue can be consumed by multiple consumer groups.
Distributed Message Service (DMS) is a reliable, scalable, fully managed message queuing service that provides concurrent access at scale using the distributed, highly available cluster technology. DMS decouples components of a cloud application, delivering substantial cost benefits.
DMS API is the main API for DMS and complies with the RESTful API design principles. You must be authenticated before using it. DMS API is deployed in the DMZ and is visible to tenants.
You can create, receive, and send messages by using the web-based management console. The web-based management console is usually used for the test purpose and DMS API is usually used for actual operation. Management console is deployed in the demilitarized zone (DMZ) and is visible to tenants.
