Wieder gab es spannende Diskussionen um das Thema SOA auf dem vwi CeBIT-Seminar zur Optimierung von ICT Infrastrukturen mit SOA und Enterprise 2.0 in Fallingbostel vom 7.-8. März 2008. Nach wie vor gibt es keine einheitliche Definition von SOA, was dann auch immer wieder zur Verwirrung geführt hat. Letztlich stimmte die Aussage von Frau Strick vom Fraunhofer Fokus: „Fragt man drei Anbieter nach SOA bekommt man fünf verschiedene Antworten darauf.“
Da ist mir das Thema Enterprise 2.0 schon lieber, zu dem ich dort berichten durfte:
Nichts desto trotz habe auch ich so eine Vorstellungswelt von SOA, wenn auch nur eine sehr einfache aus der Anwendersicht gestrickt.
The issue of “Web 2.0 vs. SOA” has been getting a lot of coverage, here is an interesting synopsis.
Dion Hinchcliffe on the Co-Evolution of SOA and Web 2.0:
“Increasingly, this has been a subject of discussion in enterprise architecture and business strategy circles (John Hagel, Andrew McAfee, Ross Mayfield), and the strange attractor story of SOA and Web 2.0 convergence is only getting more interesting and relevant to software architects and business leaders.”
The eLearning Forum has an excellent seminar and in-depth case study on a framework for “Learning Enabled Business Transformation”:
“Breakthrough technological solutions and business/process models create new opportunities for optimizing the 4 forms of intangible value/capital “Human, Customer, Partner, and Intellectual Property” to enable high performance.”
Approaches from “The Extended Enterprise” over “Strategy Mapping” and the “Balanced Scorecard” to “Service Oriented Architecture (SOA)” are covered. The first presentation lay the foundation with the relevant business context and present the framework. This is followed up by the FCC Case study. The third presentation is about solutions integration, IT architecture and implementation using the SOA approach:

Phil Windley’s write-up from the InfoWorld SOA Executive Forum.
IBM‘s web futurist David Boloker:
“Two things are at the core of situational applications: SOA (service-oriented architecture) and (…) “enterprise mash-up services” reports Ulrika Hedquist from Computerworld.
A Booz Allen Hamilton whitepaper on:
Where to Start: Service Oriented Architecture Is a Reality, But How Should You Take Advantage of It? (March 2006)
“Changing the cost equation permanently requires that CIOs reengineer their IT architectures to enable their systems to grow increasingly responsive and cost-effective over time. This has been the holy grail of IT in recent years, and in the beginning seemed just as elusive as the grail the knights looked for in the Middle Ages. Now, however, this seems to have finally changed. Many of the technologies and standards necessary to create such architectures are maturing and becoming widely adopted. After a relatively slow start, service oriented architecture (SOA) is beginning to live up to its promise.”
JP Morgenthal on the role of SOA
Strategies For Successful Integrations
“One of the first technologies to limit integration complexity is service-oriented architecture. SOA is based on open standards that allow applications to dynamically locate and communicate with a software service. SOA simplifies integration by creating a homogeneous view of existing systems and data, but it doesn’t eliminate the need to aggregate and transform across applications and data sets.
SOA has additional obstacles. It moves the processing closer to the data and application endpoints, but it doesn’t eliminate the core functionality of the broker/hubs or the information-integration engines. Still, SOA does distribute these functions across a wider array of tools, such as process, service, and semantic integration.”
