Not necessarily. What he's saying is that all services Amazon provides are going to have both internal and external customers. Both will drive the service to be better, and never get complacent. External customers will signal that the product sucks by not being customers of it. Internal customer will force the product to be reliable because if it isn't your director will hear about the costs of it not being so. Bias: 5 years at Amazon. May someday go back if the startup I joined falls.
