Subject: Subsystems communication 2004-10-20 - By Bayarsaikhan VOLODYA (YAZ-ArGe)
Back
gateways are also service-oriented anymore.
Design your gateway in such a way that can talk to both external service(remote
one) and internal subsystem.

Actually, I disagree somewhat,
IMHO, one should always strive to layer the system 2 dimensionally.
In one dimension, there are service interfaces that are use case/story
modeled, and the other,
are subsystem interfaces that may be reused across application domains,
e.g. gateways, etc.

Subsystems are a waste of time.
