Title: Orchestration v. Choreography
Discussion
Hi Folks,
Before I needed to drop off, I heard what I could agree to as a
working distinction between Choreography and Orchestration.
Choreography is what takes place in Business Process Modeling of
interactions (to some extent DesignTime work), and Orchestration is
what takes place when actual Actions are triggered by some central
conductor to produce Real World Effects (to some extent RunTime work).
The distinction between RunTime and DesignTime does not hold since
both can occur in realtime interactions that produce Real World
Effects. This was just another analogy.
I liked Frank's notion that in practice Choreography is composed
of a number of Orchestrations taking place together. I would say
taking place according to some agreed set of rules or
parameters.
I looked on the web for better analogies than symphony composer
or ballet choreographer doing Choreography and an orchestra conductor
or ballet director doing Orchestration, and found:
"Orchestration is akin to traffic lights where events are
controlled centrally, whereas Choreography is more like a roundabout,
where each participant is following a prearranged set of
rules."
