It is not perfect, but for the moment good enough:
#+BEGIN_SRC plantuml :file rabbitMQ.eps :noexport
@startuml

[Producer]

cloud {
  [Internet] as Internet1
}

node RabbitMQ {
  [Exchange]
  [Queue]
}

cloud {
  [Internet] as Internet2
}

[Consumer]


[Producer]  -> [Internet1] : Publish
[Internet1] -> [Exchange]  : Publish
[Exchange]  -> [Queue]     : Route
[Queue]     -> [Internet2] : Consume
[Internet2] -> [Consumer]  : Consume

@enduml
#+END_SRC
