RabbitMQ is an open-source message broker software that facilitates communication between various applications or components of distributed systems. It is part of the broader category of message-oriented middleware (MOM) and is designed to handle the routing and delivery of messages between different parts of a software application or between multiple applications.
RabbitMQ is commonly used in scenarios where decoupling and asynchronous communication between different parts of a distributed system are required. It’s often used in microservices architectures, for task distribution in background processing, and for handling real-time data feeds or event-driven systems.
RabbitMQ is written in Erlang and is known for its reliability, performance, and ability to handle high volumes of messages. It has a large and active community, making it a popular choice for implementing messaging systems in a wide range of applications.
