Web Services: Is it CORBA Redux? Gordon Van Huizen of Sonic Software takes the offensive to warn about improper web service implementations. "...RPC web services [have] flaws that could turn web services into this decade's CORBA...[T]hings like scheduled downtime, system failures and network outages are the reality. RPC-style web services can't cope with such intermittent behavior. [Source: Brent Sleeper]

Edging Into Web Services. From the McKinsey Quarterly.
-
The best use of Web services currently lies in applications in which connectivity problems are more complex, efficiency gains are greater in the near term, and alternative ways of connecting companies are limited...for now most companies will prefer to stick to more expensive--but proven and reliable--approaches to integrate key internal systems. Good point. At the edge there are no viable alternatives, hence another reason to start there rather than in-house where at least you've already got the EAI you love and hate.
-
Web services let companies tinker with the application while avoiding changes to the interface...[Managers] should follow three principles--leverage existing technology, implement investments in stages, and plug in new elements of the technology over time. Let's hear it for loose coupling.
-
...the new technology is essentially an overlay. Careful! McKinsey doesn't make a strong enough case for the need for an all-new way of thinking when using web services. ZapThink warns of "old wine in new bottles."
-
[A company] should be wary of creating hybrids that will limit its options when Web services alternatives become available. Proprietary extensions to fill gaps in the features of Web services, for example, should be implemented as modules with clearly defined interfaces. In this way, it will be easier to replace the proprietary extensions with evolving Web services standards as they become available. Beware of vendors who claim, "It's not just standard--it's better than standard."
Nothing altogether new here, but a good three-page article to forward to senior management. [Source: CNet's News.com]
