InfoQ posted a video of Jim Webber and Martin Fowler doing a keynote speech at QCon London this Spring. It’s a brilliant deconstruction of the concept of the Enterprise Service Bus. I can attest that they’re both funny and articulate (whether on the stage or off.)
Along the way, they talk about building services incrementally, delivering value at every step along the way. They advocate decentralized control and direct alignment between services and the business units that own them.
I agree with every word, though I’m vaguely uncomfortable with how often they say "enterprise man boobs".
