I think technology advanced faster than anticipated. In that whirlwind, a lot of companies didn't survive. The reason we have done well is because, even in that whirlwind, we kept heads-down focused on the customers. All the metrics that we can track about customers have improved every year.

If you make customers unhappy in the physical world, they might each tell 6 friends. If you make customers unhappy on the Internet,they can each tell 6,000 friends.

But there's still so much you can do with technology to improve the customer experience. And that's the sense in which I believe it's still Day One, and that it's early in the day. If anything, the rate of change is accelerating.

One advantage - perhaps a somewhat subtle one - of a customer-driven focus is that it aids a certain type of proactivity. When we're at our best, we don't wait for external pressures. We are internally driven to improve our services, adding benefits and features, before we have to.

AWS is customer obsessed, inventive and experimental, long-term oriented, and cares deeply about operational excellence.

Focusing on the customer makes a company more resilient.
