Can you explain what RabbitMQ is and how it works?

RabbitMQ is an open-source message broker implementing the AMQP (Advanced Message Queuing Protocol). It acts as an intermediary for message exchange between applications or system components, providing asynchronous communication.

How RabbitMQ works:

• The sender (producer) sends a message to the RabbitMQ queue.
• RabbitMQ stores the message in the queue until the receiver (consumer) retrieves it.
• The receiver gets the message from the queue and processes it.

Advantages of RabbitMQ:

• Reliable message delivery.
• Support for various exchange models (queues, publish-subscribe).
• Scalability and the ability to operate in distributed systems.

Example of use: an order system where an order is sent to the queue, and an order handler processes them asynchronously.
