RabbitMQ - Basic architecture | Theoretical explanation
Theoretical explanation
The basic architecture of a message queue is simple - there are client applications called producers that create messages and deliver them to the broker (the message queue). Other applications, called consumers, connect to the queue and subscribe to the messages to be processed. Software may act as a producer, or consumer, or both a consumer and a producer of messages. Messages placed onto the queue are stored until the consumer retrieves them.
