Burr Sutter neemt ons mee op een reis door de mogelijkheden van Open Source SOA. Of beter gezegd: hij geeft een overzicht van de mogelijkheden om SOA met JBoss producten te implementeren. Beetje sneaky, want in de aankondiging werd met geen woord gerept over JBoss. Burr blijkt een medewerker van JBoss te zijn en daarmee dreigt het een beetje een JBoss promo praatje te worden.
Maar dat mag de pret niet drukken, want ik ben nog onbekend met de mogelijkheden die JBoss biedt op het SOA vlak, dus ik denk: kom maar op!

In de onderstaande volgorde laat Burr de mogelijkheden zien die JBoss biedt op de volgende gebieden:
- Webservices gegenereerd uit annotation based POJO’s (JSR-181 Annotations)
- BPEL support gebaseerd op jBPM
- JBossESB
- Content Based Routing op basis van JBossRules

Hij legt keurig uit wat elk concept betekent, wat een webservice is, waar een service aan moet voldoen en vervolgens wordt voor elk onderwerp een demo gegeven.
Helaas was de verlichting in de zaal niet al te best waardoor de slides slecht leesbaar waren en de demo’s helemaal niet te volgen waren.

De conclusie van de presentatie is toch wel dat JBoss inmiddels veel meer is dan enkel de applicatie server waarmee JBoss bekend is geworden. Het JBoss platform wordt steeds completer, de ondersteuning op het gebied van SOA wordt steeds groter. Het lijkt een serieuze kandidaat om SOA mee te implementeren, zeker als open source belangrijk is, of de voordelen daarvan belangrijk zijn.
Hoe compleet het platform daadwerkelijk is en hoe gemakkelijk het te leren en te gebruiken is, is op basis van deze presentatie van een uur uiteraard niet te bepalen.

This article is the first in a series exploring the various technologies and options available to an enterprise when establishing a service-oriented architecture (SOA) roadmap. It introduces the notion of an SOA infrastructure and enriches it with the models and frameworks currently available to SOA implementers. By describing architectural components and frameworks common to SOA, it defines the baseline for the service-oriented enterprise. Subsequent articles will further explore a possible methodology for SOA governance based on the formal description of the purpose of each service. This methodology provides diagrams and template examples of inputs and outputs on the decision paths needed for SOA adoption and roadmaps [REF-1].

Introduction

If you have been in the IT field for a while, you can’t help but get the feeling of déjà vu when you hear vendors pitching new technologies. If the buzz and hype around Service Oriented Architecture (SOA), makes your head spin, you are not alone. In a recent meeting, one participant who used to code in COBOL asked what was different between SOA and what he did with COBOL copybooks. I have never used COBOL copybooks, but having seen many technologies come and go, I can empathize with the question. In this article, I explain the primary motivation behind SOA and how technology has evolved to support SOA. I will keep my discussion at a conceptual level and refer to other publications at the end for those who want to delve deeper.
