Re: [soa-rm] What is SOA (Really???)

["Sotudeh, Kooros \(US - McLean\)" <csotudeh@DELOITTE.COM>]

True ... in the situation that the functionality is the same and yet the
new service offers better SLA, faster response etc., I would suspect
that the governance one should have in place would mandate depricating
the old service in favor of the new.  This should include properly
addressing the inclusion/modification of the registry, discovery of
services, metadata, etc.  If the new service truly extends the old one
to include added functionality, it's perhaps a valid case of
multi-service composition.  Still, IMO governance is the key.

Best,

But surely if your service offer includes a better SLA, faster response
time, better quality of result, etc. it is not a duplication of a
service
but a different service: it may however use the same resources, and that
is
a different issue...

This gets into the hairy realm of governance.  I could argue that you
should
not be funded to develop a service because I provide adequate
functionality.
However, you may respond that my quality of service stinks and you'll do
better.  On the other hand, I want to extend the functionality of your
service but to do that I will be duplicating everything you can do.

This goes on and on.
