Yes. If we accept Don Box's definition, I find myself
puzzled about service autonomy over shared resources if
any. If a service can't share a resource, it's a method
with private data (even if the data is in a database and
not an object). So all I'm left with is the granularity
difference and is that really a difference?
It seems to be a terminology designed to sell the
implementation framework and hide the details: that is,
like ecosystem diatribes, it's metaphorical.

And a fundamentally different level of communication
failure potential.
I guess, to some, these differences are not only
practical but also fundamental. I have seen a few
such disussions back in the CORBA days.

Makes sense.
