notes, "The real test of one's ability to hang onto customers will not come when maintenance contracts expire but when the major software companies, Oracle, SAP, Microsoft and to some extent IBM, transition to so-called 'service oriented architectures,' a fundamental change in the way applications are deployed, integrated and accessed."
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.

Acknowledging that there is now "more hype than actual work" in the field of SOA, David Linthicum, a profilic author and host of SOA Expert Podcast, offers several patterns of success to think about as one puts their SOA plans to work. "These patterns are not always obvious, so perhaps this is a good time to learn through the successes of others and do our own homework before we spend millions on moving to an SOA," he says.
Can having services bought and sold on an open market change the way software is delivered?
A chat (transcribed here) between Bill Gates and InfoWorld's Jon Udell at Microsoft's Professional Development Conference covers a lot of ground around Web services development (XML) on the Microsoft platform. ZDNet colleague Dan Farber calls this interview with Bill Gates "one of the better interviews" he's heard or read over the past two decades.
Enterprise software consolidation -- such as that resulting from Oracle's Siebel acquisition -- may provide the kick in the pants needed for major SOA projects. My ZDNet blogging colleague Dana Blankenhorn points out that "Oracle is now Microsoft," meaning they are the consolidation kings.
IBM announced an exhaustive list of initiatives around SOA, including new software and service initiatives. Perhaps what raised the most eyebrows at the product launch briefing was the introduction of two enterprise service buses (ESBs) -- one for simpler installations, and another for environments requiring a more sophisticated message broker.
SOA and BPO (business process outsourcing) aren't a natural match, apparently. Some think the two together can even unleash the forces of chaos.
Fellow ZDNet commentator Phil Wainewright (author of the recently launched Software as Services Weblog) asks an interesting question (at his LooselyCoupled.com site) pertaining to BEA's planned acquisition of portal vendor Plumtree Software.
One of the interesting aspects of new service-focused business models -- related to SOA and SaaS -- is their concentration on new pricing models. As opposed to requiring payment upfront, these models enable customers to pay on a subscription or incremental basis.
The road to SOA success is replete with potholes. With this in mind, ZapThink's Jason Bloomberg offers this list of 7 things you "shouldn't say" during your enterprise architecture team meetings:
