RabbitMQ - Message Broker

RabbitMQ is a powerful open-source message broker that implements the AMQP (Advanced Message Queuing Protocol) protocol. It enables applications to exchange messages asynchronously through queues, providing reliability, scalability, and decoupling of system components.

RabbitMQ is widely used for building microservices architectures, handling background tasks, and implementing event-driven architectures.

Messages Stored in a Queue

A consumer retrieves messages from the queue.

The consumer acknowledges processing (acknowledgment) of the message to ensure reliable delivery.
