Message Service (MNS) allows you to use the queue-based messaging model or the topic-based messaging model to send or receive messages. This helps implement the one-to-one or one-to-many consumption mode. This topic describes how to get started with MNS.

Queue-based messaging model: MNS queues are used to send messages from a producer to a consumer.
Topic-based messaging model: MNS topics are used to send messages from a publisher to multiple subscribers.
Get started with the queue-based messaging model
In this example, messages are sent or received in the MNS console, as shown in the Use the queue-based messaging model to send or receive messages figure.
