Web Services Strategies
Beyond the technology, IT strategies for implementation of Web services by Doug Kaye.

Ten Emerging Best Practices For Building SOAs. In the February 25 issue of ZapFlash, Jason Bloomberg gives his recommendations " to leverage the power and flexibility of Web Services strategically across the enterprise." One of my favorites:
The enterprise application story of the 1990s was all about suites. Buying a few large packages with several tightly integrated modules made more sense than going with a best-of-breed, "mix and match" approach, so the argument went, because integrating products from multiple vendors was such a nightmare. Web Services and SOAs reverse this argument, because Web Services can reduce the cost of integration to the point that best-of-breed approaches make solid economic sense.
And another of which Jason was the earliest champion:
One of the holy grails of software development is code reuse. In an SOA, developers should construct the Services to be as simple as possible, where they continually refactor them so that they are as broadly applicable as is practical. The resulting services are then reusable at runtime-nuggets of software functionality (both fine- and coarse-grained) that can be used in a variety of situations, as contrasted to typical code reuse, which is a design time principle.

Don Box: Too Many Specs. The co-inventor of SOAP (now a Microsoft engineer) had harsh words this week for vendors contributing to the plethora of web-services specifications, and advised developers to read less of them and get on with writing applications.
Also from the XML Web Services One conference, Anne Thomas Manes, now with the Burton Group, said that upcoming specifications like WS-Security, being hammered out by Microsoft, IBM and Verisign Inc., will be useful for some, but in the meantime the existing SSL (Secure Sockets Layer) security standard "solves 80 percent" of security needs for Web services.
