Subject: Re: [ebsoa] Ben's document
I've added to David's excellent list of patterns below. I'm headed back to New Orleans next Wed morning to present SOA (general concepts, benefits, etc.) at a DOD conference, and I'm considering incorporating the notion of patterns into my presentation.

How about these possibilities: 5) Infrastructure - utilizing an SOA for infrastucture-type services such as security, logging, discovery, etc. 6) Calculation - where part of the SOA provides a calculation result based on input values (such as calculation of APR for a loan); but this would be a pattern for a "segment" of an SOA, rather than an SOA overall. *** Maybe we need to think about "sub-patterns" as well? *** 7) Transactional - utilizing an SOA for transactional-based processing, such as the submission/processing of a PO to receive an Invoice. 8) Notification - utilizing an SOA for notification-type services such as a calendar service that sends notifications to other calendars when an appointment is changed; 9) Others? > What I'm chiefly after here is avoiding being button-holed. > > Ben's approach to SOA - while good for todays programmers > can also suffer from rapid obsolescence - as witnessed from > people touting POA, and varients already today.
