Message Queue summary and queue Summary

Message Queue summary and queue Summary

I. First, let's take a look at the common use cases of Message Queues:

• Asynchronous Message notification (SMS or email)

• Application decoupling (Order and inventory)

• Traffic buffer (second kill)

• Log Processing

• Message reliability (persistent, can still be used after restart)

 

Ii. Two Message Queue specifications and their comparison

Currently, the two main message specifications are JMS and AMQP. The comparison between the two is as follows:

• AMQP can be used across languages and platforms; JMS can only be used in Java

• The JMS message model only includes: point-to-point and publish subscription, while AMQP supports more flexible message models, such as (Direct, Topic, Headers, and Fanout)

• JMS representative: ActiveMQ; AMQP representative: RabbitMQ
