Brief introduction

MQ is all called the message queue, and Message Queuing (MQ) is an application-to-application communication method. Applications communicate by reading and writing messages to and from the queue (data for the application), without requiring a dedicated connection to link them. Message passing refers to the process of communicating between programs by sending data in a message, rather than by directly invoking each other, and directly invoking techniques such as remote procedure calls. Queuing refers to an application communicating through a queue. The use of queues removes the requirement that both the receiving and sending applications execute concurrently. Some of the more mature MQ products are IBM WEBSPHERE MQ and so on.

• Several concepts

Exchange: A switch that determines the message routing rules;

Queue: Message Queuing;

Channel: Access to read and write messages;

Bind: Binds queue and exchange, which is the message queue that conforms to what routing rules it will be placed in;
