Amazon's 'Two-Pizza Team' Mandate

Jeff Bezos issues a famous mandate across Amazon: all teams must be small enough to be fed by two pizzas, and must communicate with each other exclusively via well-defined APIs and services. This internal architectural shift laid the groundwork for AWS.

Significance

This mandate forced Amazon's internal systems to de-couple, becoming independent, discoverable services that could eventually be productized and offered externally, directly leading to the AWS concept.
