SOA creates new opportunities for business-IT collaboration

The SOA wave – which promises to embed business processes in code – will drive tighter alignment between business and IT, according to a recent piece in Optimize Magazine. Citing Forrester Research analyst Randy Heffner, the article makes the case that IT development roles and responsibilities are shifting.

I am not sure I agree with the characterization "promises to embed business processes in code " fact that is exactly what we want to avoid, but I am sure that the writer did not intend to imply the negative...

Liberty Alliance extends support for SAML 2.0

The Liberty Alliance and OASIS have reached another milestone in their collaborative efforts to drive the convergence of identity standards. Last week, the Liberty Alliance released the public draft of its Identity Web Services Framework (ID-WSF) 2.0 specification, which has been extended to support the OASIS SAML 2.0 specification. SAML 2.0 is expected to be officially ratified as an OASIS standard in March 2005. By leveraging the latest iteration of the ID-WSF framework, developers can use SAML assertions to communicate identity information such as authentication status, user attributes and authorization decisions between identity-based Web service transactions. see here

Financial Industry Floats Messaging Standard for SOA

A coalition of financial institutions is working to develop an open-source alternative to proprietary message queuing technology, hoping to make Web services and service-oriented architectures fit for duty on Wall Street.The new technology, known as AMQ, is an open-source message queuing system that provides the same functionality as IBM's WebSphere MQ (formerly known as MQSeries), has implementations on C and C++, and will support C# and Java.John Davies, vice president of New York-based JPMorgan Chase & Co., which is participating in the development project, said several million dollars have been spent on AMQ R&D. IBM and fellow proprietary messaging company Sonic Software Corp. are closely following the project, Davies said."We now need something that's not proprietary. Banks don't like proprietary things," Davies told eWEEK during an interview at the Web Services on Wall Street Show & Conference here last week Read full article here

The Missing Link Between Business and Web Services?

"The enterprise service bus (ESB) is, arguably, emerging as the preeminent platform for building, deploying, and managing Web services. However, once you have created and deployed your Web services, what's the next step? For many developers, it is the orchestration of those services into composite applications and business processes. In the past, this area has proved troublesome. ".....summary of article written by John O'Shea in WebServicesJournal .

Web Services Protocols and Stack Summary

The reports by CBDI assess the status of various Web Service protocols and suggest a timeline for their adoption and relevant roadmap actions. They provide a useful reference and links to all the numerous protocols currently proposed or in the standards process. I have found the summarys useful for getting a broad overview of the WS-\* landscape, however in spite of the attempt by CBDI to cover everything, I find there are still few standards that have not been mapped in.

Bottom-up SOA Just Gets You the “A”

This turns out to be a Top-Down vs Bottom Debate that Thomas Erl is having on his weblog on Thomas seems to have the feeling that SOA is only achieved by a top down approach and a bottom approach does not even put you on the path to SOA. My Take....I disagree with achieve SOA you actually have to have the top down as well as the bottom up....those that take the either or position are missing the hard parts of implementing a SOA. The point is to move to SOA you must deal with the TOP and BOTTOM..and for that matter the Middle also... read his post here

Standard BPM Stack as defined by

This is's take on the BPM standads stack.....I am not endorsing or advocating this stack..just making it available for informational purpose. See the stack here "not rivaling" BPEL

Is BPXL a rival of BPEL? says no...If I was a betting man I would put my money down on BPEL and BPMN...but the jury is out as far as I am concerned on the story here

Loosely coupled invention

A good example of unintended consequences is spelled out in a a great blog post by Phil Wainewright on Hey maybe there is more to SOA than hype.......

I served as Chief Architect of Sun's Developers Tools and recently took on the challenge of managing the Sun Learning Services global technology architecture and infrastructure as Chief Technologist of Sun Learning Services.
