Dave Chappell
Now the software engineer spends most of his time teaching developers and engineers around the world how ESB technology can help them. The ESB allows enterprises to build service-oriented architectures in a loosely coupled and highly flexible fashion that’s scalable and fault-tolerant, Chappell said. The key to building SOAs is having flexibility through changes in configuration, not coding, he said.
As vice president and chief technology evangelist at Sonic Software, Dave Chappell, 43, literally wrote the book on the Enterprise Service Bus, but the software engineer didn’t start out wanting to be an author.
This self-taught software engineer got his first job working for a mail-order company that sold software to developers and eventually moved into development himself. By the late 1990s, Chappell was leading the Sonic engineering team in the development of SonicMQ, an e-business messaging server, and the Java Message Service (JMS), the core messaging component of the Sonic Enterprise Service Bus.
One afternoon while working on JMS, Chappell was walking down the hallway at Sonic, Bedford, Mass., when he took a call from Richard Monson-Haefel, who was interested in learning more about JMS. They started chatting and wound up collaborating on their now-popular and influential book, ’Java Message Service.’
