Message passing refers to the process of communicating

The main features of AMQP are message-oriented, queue, routing (including point-to-point and publish/subscribe), reliability, and security.The main thing to say in AMQP is two components: Exchange and queue (there are also changes in AMQP 1.0), as shown in the following figure, the green X is Exchange, the red is the Queue, both on the Server side, also called the Broker, which is part R ABBITMQ is implemented, while the blue one is the client, usually there are two types of Producer and Consume
