Following on the heels of the excellent
"SOA Governance
and Management Methodology"
session, IBM's Rob
High is laying out the Foundations
of Service Oriented Architectures.
He is focusing at a high level of looking at "services" as the
bridge between business processes and information technology processes.
What is good is that he says it does not matter what technology you are
talking about, the business owners do not care about what technology is
used for the services (J2EE, .Net, Cobol, etc), they just see the services
as delivering what they need (not an IBM rah rah approach). That is why
it is important that services are independent of the underlying IT Architecture.
