So why don't we keep the diagram at a more conceptual level and not talk
about specific technologies, per George's suggestion:

Four boxes, two pillars:

  S    M
  E    A          Processes
  C    N  --------------------------
  U    A          Services
  R    G  --------------------------
  I    E          Messages
  T    M  --------------------------
  Y    T          Transports
