[AG-TECH] ag2.2: pig vs. node proper

While i most certainly do appreciate the answer, it was not quite what i
was after. i am aware that AG can be spread across multiple machines (and
that physical machine configurations don't matter so much as long as all
AG software components are running somewhere and can find each other).

What i am after is a system level break-out of the software components:
which python script is doing what, specifically in the multi-machine
configurations.

Thank you.
