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

Web Services Too Slow? HSN, Inc. (formerly known as Home Shopping Network) opted out of turning the search engine (200,000 serches per day) on its retail-oriented web site--hsn.com--into a web service, which was their original plan. Apparently they thought an architecture based on web services would be too slow for their application. But the article doesn't suggest that HSN actually ran tests or at what level in the architecture they considered using web services.
Also covered in the article is a case study of how American Electric Power in Columbus, Ohio, will be using web services to "pull data out of its PeopleSoft human resources system." This strikes me as merely using web services as a data-extraction API and not taking full advantage of a service-oriented architecture. But perhaps that's all you can do with packages like PeopleSoft for now, until they're re-written using a true service model.

Another Good Executive Intro. This one comes from Michael Jarosik at Start Magazine and is posted on Grand Central Communications' site. A few highlights:
- Jarosik explains that web services aren't the application but the framework.
- He points out that for tactical implementations, you're likely to turn to existing vendors for your tools: your EAI vendor to add web services to an EAI package, or your application server vendor to add web-services interfaces there. However, once you're ready for more strategic deployment of web services, the investment requirements become much more complicated.
- Mike Gilpin of Giga is quoted regarding the advantage of using a single technology for both application development and integration. (Traditionally, it's been my experience that these are handled by separate teams using different tools.)
- Jarosik points out that there are three ways for users to interface with web services: (1) via portals, (2) through legacy apps such as CRM, and (3) via alerts.
