Exchange types in an AMQP messaging protocol

There are several types of exchanges in AMQP protocol

• fanout - messages are published to all queues
• direct - messages are delivered if the message's routing key is identical to the queue's binding key.
• topic - The exchange routes messages to the relevant queue or queues, depending on matches between the routing and binding keys
• header - headers of the messages, and the binding key constraints of the queues are used to determine the correct queue/queues

A good article about the above is explained in detail in the following article.
