I like JMS enough, but it has its issues. If there is a better, simpler way to do service orchestration I'm all ears.
Master/Worker with spaces might work. What else?
I like location transparency. It’s neat.
Update 27-DEC-2006 Just tickling your RSS reader - some good comments on this post. Please chime in if you have an opinion. I am becoming fascinated with this topic. There are a lot of parallels between SBA/distributed caching and EDA service orchestration models. I'm spending some time getting my hands dirty trying to get my head around it better.
