RabbitMQ Message Broker

RabbitMQ is a popular open-source message broker that functions as an intermediary for communication between different software applications, a core component for building robust distributed systems. It decouples services by allowing producers to send messages to an exchange, which then routes them to specific queues based on predefined rules, without the producer needing to know about the final consumers. By implementing the Advanced Message Queuing Protocol (AMQP), RabbitMQ provides a reliable and scalable platform for managing asynchronous tasks, distributing workloads, and building resilient, event-driven architectures like microservices, ensuring messages are delivered even if parts of the system are temporarily offline.
