Rabbitmq

Implementing a communication model where the publisher sends messages to a message broker, and the subscriber receives messages from the message broker. In the pubsub (Publish-Subscribe) model, the publisher does not send messages directly to the subscriber but sends messages to the message broker, which then forwards them to the registered subscribers.

RabbitMQ is a message broker used for sending and receiving messages using the AMQP (Advanced Message Queuing Protocol) protocol. A message broker is software used to send and receive messages between applications or systems in a standardized way.
