You Build It, You Run It

Giving developers operational responsibilities has greatly enhanced the quality of the services, both from a customer and a technology point of view. The traditional model is that you take your software to the wall that separates development and operations, and throw it over and then forget about it. Not at Amazon. You build it, you run it. This brings developers into contact with the day-to-day operation of their software. It also brings them into day-to-day contact with the customer. This customer feedback loop is essential for improving the quality of the service.

Most of the code in the system should be written with the assumption that the input data to the function in question is correct. Only a small part of the code should actually perform any checking of the data. This is usually done when data enters the system for the first time, once data has been checked as it enters the system it should thereafter be assumed correct.
