• Client consumes messages from Queue

• Messages from Exchange are routed to Queue based on condition specified by Binding

Exchange types• direct - exact match of message’s Routing Key and

binding’s one

• topic - basic routing based on wildcard matching of Routing Key treated as zero or more words separated by «.» («*» - single word, «#» - zero or more words)

• fanout - simple broadcast

• headers - more complicated routing based on custom headers matching
