Conventional wisdom is a curious thing, especially when applied to a technology as new as Web services. Web services are often thought of as distributed business processes participating in a B2B relationship using Internet protocols and XML-based data standards. In fact, much of the introductory literature on Web services emphasizes that while most modern Web applications are designed to be used by human beings sitting in front of a browser, Web services are supposed to be used by some sort of automated service requester. The examples given in such texts frequently support such assumptions, but is this the only useful scenario? In a typical B2B relationship, the actual client application logic is likely to be found in the middle tier of a distributed application of some sort. Frequently, but not exclusively, this middle-tier logic is a business object in the form o... (more)

Snow White's FIRST Web Services

One day, Snow White decided to deploy a Web service. Her IT dwarves immediately went to work and were pleasantly surprised to find how easy it was to create the Web service using modern development tools. To Snow White's development dwarves, it almost seemed like magic. Since Snow White's cottage was a Java shop, they deployed the Web service in their J2EE application server, but they could have just as easily used .NET and it would have seemed just as magical - maybe even more so, given the wealth and power of the Wizard of Seattle. Since Snow White had lived in a palace with a ... (more)

The Well-Spoken SOA - How Well Is Your SOA Running?

The American comedian and actor Steven Wright once said, "It doesn't make a difference what temperature a room is, it's always room temperature." Words are wonderful that way. They can give you a little blast of pleasure when used cleverly, but like everything else they are subject to fashion. For example, I was speaking at a technical conference recently when I overheard a person whom I know, who is well-respected in this field, say something along these lines: "You have to know how well your SOA is running. Knowing the overall health and responsiveness of your SOA is very impor... (more)

Governance, Security, and Management in a Service-Oriented World - When New and Old Collide

Significant investments in the successful management and administration of many critical business systems have had mixed success over the years. In a new, more competitive age of regulation and globalization, SOA promises much in terms of business agility and efficiency, but how do we maintain visibility, control, and appropriate governance of this new and much more highly distributed service-oriented world? Most authorities in this field agree that management and security are complimentary foundations of an essential framework for SOA success, but what does that really mean and ... (more)

Composition and Management of Web Services

Father James Keller, the founder of a religious order called The Christophers and a popular religious television and radio personality in his day, wrote an amusing story about Mozart. He said, "A young man, just beginning the study of musical composition, once went to Mozart and asked him the formula for developing the theme of a symphony. Mozart suggested that a symphony was rather an ambitious project for a beginner; perhaps the young man might better try his hand at something simpler first. 'But you were writing symphonies when you were my age' the student protested. 'Yes, but... (more)
