RabbitMQ: Open Source AMQP Message Broker

RabbitMQ is an open source message broker that implements the Advanced Message Queuing Protocol (AMQP). It is designed to receive, route and deliver messages between applications flexibly, reliably and at scale.

What is RabbitMQ?

RabbitMQ is an open source message broker software that implements the Advanced Message Queuing Protocol (AMQP). It is written in the Erlang programming language and developed originally by Pivotal Software. RabbitMQ allows different applications to connect and pass messages between each other in a very flexible way.

Some key features and capabilities of RabbitMQ include:

  • Support for queues, exchanges, bindings and routing keys to flexibly route messages
  • Persistence options to make sure messages are not lost in case of failures
  • Clustering and federation options for high availability and scalability
  • Pluggable authentication and authorization backends
  • Management UI and HTTP API to monitor and control the system
  • Client libraries for many programming languages allowing easy integration
  • Active open source community providing support, troubleshooting and feature development

RabbitMQ is used in many distributed systems to decouple applications and improve communication while minimizing coupling. Its flexibility makes it suitable for integration tasks in SOA architectures as well as more modern microservices architectures. Companies like NASA, EA and Spotify use RabbitMQ in production.
