Also Know, how does RabbitMQ work? RabbitMQ works by offering an interface, connecting message senders (Publishers) with receivers (Consumers) through an exchange (Broker) which distributes the data to relevant lists (Message Queues).
Also, why do we need routing key in rabbitmq?

In respect to this, what is rabbitmq amqp model?
The conceptual model of AMQP is quite simple and straightforward . It has three entities: When a publisher pushes a message to RabbitMQ, it first arrives at an exchange. The exchange then distributes copies of these messages to variously connected queues. Finally, consumers receive these messages. Consider a message as a piece of data.
