Yefim Natis is sure that ""SOA is integration"   Message List

Re: [service-orientated-architecture] Re: Yefim Natis is sure that ""SOA is integration"

Not really, the argument appears to be more about what is integration,
for instance whether process and choreography count as integration
and whether more dynamic interaction models count as integration.

I think that most people on this list agree that SOA is
_predominately_ a governance/organisational/business/thinking thing,
but that there are SOA _technologies_ which are related directly to
implementation. One of the on going challenges in this group is the
two different worlds of SOA.

Far from being vacuous that is in fact the biggest and oldest
challenge of IT and the point of SOA is that it can have the
discussion on both sides but its failing is that it still hasn't made
the difference clear.

Define integration in a tight and specific way.

Steve

Doesn't the suspicion that SOA is vacuous grow stronger when you see that we can't even agree about the relationship of SOA and integration?...
