Hi JP - I am not sure what you think SOA Infrastructure means, but to me it means the technology needed to implement an SOA based application - i.e. an application designed using an SOA.
The coin in this case has two sides - yes, SOA based design is independent of technology. However, technology is needed to implement the design. I fail to see a problem in calling that technology "SOA Infrastructure." Best, Eric --- JP Morgenthal <[EMAIL PROTECTED]> wrote: > Sorry, but I have to weigh in on the title of this > thread.
