RabbitMQ
What is RabbitMQ? RabbitMQ is an open-source message-broker software. It has implemented the Advanced Message Queuing Protocol. RabbitMQ works very similar to a post box. The producer i.e., the originator of a message will send the message to post box and than the message will reside inside post box until the message is handed over to the consumer/receiver. In rabbitMq instead of a postBox we will use a queue. This queue will retain the messages until taken by the consumer. The main benefit of using this message broker is that the producer and the consumer don’t need to understand each other language. that is a consumer can be written in javascript and a consumer could be a java program. They just should know how to connect with RabbitMQ queue. For example : here is a simple program to show a producer, consumer and a queue. This is a sender program.
