Just when the world is starting to figure out the nuances and applications of WSDL (Web Services Description Language), a new way of describing Web services messages has been thrown into the mix. A new "experimentalframework" for Web Services description -- called the SOAP Service Description Language (SSDL) -- has just been released.
Service technology -- from SOA to cloud to IT service management -- promises many "-ilities": greater agility, flexibility, and reusability. Joe McKendrick explores the challenges and opportunities with service orientation, and how to capitalize on these emerging computing philosophies.

We've entered the "practical phase" of Web services, says Halsey Minor, CEO of Grand Central in a recent interview with Business Week. "The first phase was a bunch of people designing a whole bunch of standards -- primarily those were a bunch of computer scientists.
Over the past week, fellow ZDNet bloggers George Ou and David Berlind have been discussing the potential and peril of grid computing. George points to some of the impracticalities of grid between organizations, and the fact that grid may be the wrong answer to other infrastructure issues.
Jon Fancey provides a good explanation of BPEL (Business Process Execution Language) now posted on Microsoft's MSDN site. BPEL scripts will serve as the orchestration glue between various Web services to make the whole SOA work.
Maybe it's a sign we're relying on IT too much when we "outsource" our Valentine's Day sentiments to the Web infrastructure -- and things can and do go wrong.To quote writer Dave Barry, the way to remember your anniversary is that "it's the day before you have to buy a very expensive present.
The Gartner gang may see great things on the horizon with Microsoft's upcoming Indigo platform, but a "show-me" attitude reigns in the IT trenches. ComputerWorld's Heather Havenstein took the pulse of users at Microsoft's VSLive conference in San Francisco, and found plenty of healthy skepticism.
Gartner is bullish on Indigo, Microsoft's upcoming Web services deployment and communications platform. Since Microsoft dominates up to 90% of the client-side or desktop computing market, the new Web services features will see significant adoption as the next version of the Windows operating system (Longhorn) rolls out.
Redmonk's James Governor alerted us to the potential of REST as a simpler alternative to SOAP (see my previous post), and also shed the spotlight on another under-reported spec that could make life simpler: ebXML (Electronic Business using eXtensible Markup Language).ebXML is a modular suite of specifications that provide a standard method to exchange business messages, conduct trading relationships, communicate data in common terms and define and register business processes.
Gartner estimates that about 10 percent of organizations now use UDDI, and makes another prediction: that UDDI may eventually merge with other specifications, including ebXML Registries, "which are used as much as UDDI."Gartner only foresees about 20 percent of new projects in Global 2000 companies adopting UDDI by year-end 2007.
"If you want to have more flexible, adaptive business processes, move your IT applications to SOA," says Meta Group analyst Janelle Hill in a new article in Intelligent Enterprise that profiles some SOA success stories.One of the companies profiled in Michael Voelker's excellent piece is Glen Allen, VA-based Owens & Minor, a respected distributor of medical and surgical supplies.
