Fred Cummins, an EDS fellow, and SOA veteran, wrote an essay last week on "Data Management for SOA". He is looking at how some of the key tenets of service design ("loose coupling" and "autonomy") relate to enterprise data in the context of achieving reuse and enabling change.
Mike Matsumura has produced a SOA wordle (word cloud) that is interesting to look at, but is it an accurate reflection of SOA?
SOA is introducing new and complex processes and technologies while aiming at achieving challenging goals for the enterprise. A SOA Consortium panel discusses the importance of establishing a SOA CoE with a broad set of skills as a key success factor for delivering SOA.
With SOA 2.0 dead and the REST vs SOA vs Web Services debates simmering less fiercely of late, some in the industry have started to talk about Web Oriented Architecture (WOA). But is this different to anything that already exists (e.g., REST)? If so, why and how does it help developers and deployers? Burton Group's Anne Thomas Manes believes it is a term too far and adds nothing to the debate.
Good governance of a service-oriented architecture is becoming a core competency. SOA governance is about ensuring and validating that assets and artifacts within the architecture are operating as expected and maintaining a certain level of quality. Newly released Repository Manager from SOA Software provides many features, that are required for successful SOA governance implementation.
Despite increased adoption, many of the SOA projects are still failing Things are often getting so bad that in a recent SOA was called "Dead on Arrival". One of the ways to improve this situation is proper SOA governance.
A recent ebizQ podcast with IBM's Lief Davidsen discusses how ESBs can be used as the simple solution to adopting SOA. The "should I or shouldn't I?" debate around the relationship between ESB and SOA has raged for a while and this interview will probably not be the final word.
While SOA was the big name in the buzzword tag cloud, BPM is quickly getting bigger and bigger. As organizations are becoming more aware of the need to tame their processes in order to get the benefits of IT investments, BPM is gaining importance and mindshare inside and outside of IT. Is one more important for your architecture?
SOA has often been described as a longer term development pattern than the hype surrounding it would often imply. However, many authors have frequently pointed out where some or all of the practices involved within SOA have been used over the past few decades. Kirstan Vandersluis goes further and discusses specific generations of service-oriented development that have lead to today's systems.
Several new resources are available for the software architect. Simon Brown and Kevin Seal have made available a set of guidelines for creating software architecture documentation. Mike Kavis also put together a framework to help guide the architect in dealing with the change that new architecture can bring.
People have thought of establishing a relationship between SOA and Web 2.0 for quite some time yet these two cultures are generally failing to cross-pollinate. InfoQ spoke with Marc Osofsky and Dave Gynn from Optaros, a consulting company which is delivering solutions using Open Source, SOA and Web 2.0. We discussed enterprise-readyness, component selection and rapid delivery methodology.
A Gartner Report elaborates how emerging Event Driven Architecture and Service Oriented Architecture programming models, as well as the continued growth in adoption of key open source technologies (in particular Spring) have all combined to put significant pressure on traditional platform middleware vendors and may lead to disrupt the industry landscape.
SOA is often understood in terms of technical tools and software solutions. Dan North believes that this may prevent architects from focusing on its essence: thorough mapping and modeling of core business processes. He shows how to design SOA in a "technology-agnostic" way so that business can play an important role in identifying SOA requirements without being constrained by technical decisions.
NServiceBus is an open source communications framework that will help guide developers who are trying to build enterprise .NET systems, without falling into many of the typical pitfalls. It provides scalability critical features like publish/subscribe support, integrated long-running workflow and deep extensibility.
A recent Zapthink report discusses the granularity of services and how atomicity or composibility factor into the design. The result is a matrix that shows the potential trade-offs to be made when developing your services.
