Fanout exchanges are ideal for the broadcast routing of messages. In rabbitmq (and amqp in general), an exchange is the abstraction and routing entity to which messages are published to, from external connecting applications. Topic exchanges route messages to one or many queues based on matching between a message routing key and the pattern that was used to bind a queue to an exchange.
