In it, Ross Mason (from the Mule project) argues that “Despite vendors’ friendly talk about their approaches to SOA, ESBs, and integration in general, their practices are often predatory . . . Vendors have been sticking it to enterprise cusomers for a long time.”
The five ways, for those who’d like to avoid gouging, are:
- Up-front Coding, Proprietary Toolkits
- Astronomical Licensing Costs
- Ongoing Services / Support Costs
- Getting Locked Into a Prescribed Approach
- Feature Overshot
Mason concludes that “open source is giving enterprise customers alternative approaches to integration . . . [which] leave your options open, reuse your existing technology investment, and put you in the best position to be able to pick and choose complementary approaches.”
Well worth a read if you’re in the position to deal with EAI, ESB, SOA, or WS-* type projects, whether commercial or open source applications are being leveraged.
