What is RabbitMQ and what are the use cases of it ?

Question

One server may have support of limited number of physical interfaces. What if there is need of more Ethernet interfaces but physical slots are not available ?

Answer 1

RabbitMQ is mainly used as a messaging middleware between applications. You can think of it as a message queue between various components of the system. With the advent of micro services architecture, where you have server applications deployed as a bunch of micro services running on different computing modules, its becomes necessary to have a queueing mechanism between then for inter process communication.

Traditionally this was done in house by creating a socket based API , but now RabbitMQ and Kafka based middlewares make the programming a lot more easier and the best part is that they scale very well with the application and requests.

Hope this helps.

Thanks to share your knowledge. Can you please tell me where exactly it is frequently used other than middle-ware ?

While going through one of the openstack reference link, RabbitMQ was mentioned saying Nova components communicate to each other using AMQP (Advanced Messaging Queuing Protocol) like RabbitMQ. If I get something interesting, I'll share with you.
