RabbitMQ is a simple/traditional publish-subscribe message broker. It is usually used as middleman, where a system simply needs to notify another part of the system to start to work on a task, like ordering handling in a webshop (order placed, update order status, send order, payment, etc.). Another main use case is for long-running tasks or when you want to perfome reliable background jobs.

  

It can be used when web servers need to quickly respond to requests. This eliminates the need to perform resource-intensive activities while the user waits for a result. RabbitMQ is also used to convey a message to various recipients for consumption or to share loads between workers under high load (20K+ messages/second)

  

  

In current version the exchange type is default and the queue name is considerd the routing Key.
