We spend a lot of time these days talking about governance and management when it comes to SOA. There’s a good reason to take that macro view, because far too many people get lost in the trees and fail to see the forest when it comes to service orientation. We are talking about enterprise architecture after all, so an enterprise-level view would be appropriate.
That said, you can put the perfect governance model in place and it won’t mean a thing if you don’t understand messaging. SOA requires a lot of integration work and integration, more often than not, requires messaging. With that in mind we created a messaging lesson in our Service Orientation for Architects School. It features a Webcast with WSO2′s Paul Fremantle on service-oriented messaging, in which he breaks down a slew of messaging alternatives, including JMS, HTTP, REST, SOAP, WS-Addressing, WS-ReliableMessaging and traditional message queues.
Yet more than that, Fremantle delves into messaging practices that will aid you on the SOA front. It’s one thing to boil up a big pot of integration spaghetti, quite another to architect a reliable messaging infrastructure. The lesson is focused on the latter.
The goal of mediation is to help create a flexible messaging backbone for your company. The tip covers a host of mediation techniques, including Web Caching, load balancing and message-based routing.
It’s an ideal chance to catch up on the architectural underpinnings of messaging as they apply to SOA. Even for those of you who feel fairly confident about your messaging skills, this lesson is sure to give you a few pointers to hone your skills.
