Jeff Bezos's API Mandate

Jeff Bezos issued an infamous company-wide mandate stating that all teams must expose their data and functionality via service interfaces, communicating solely through these interfaces. This directive forced a complete re-architecture towards a service-oriented model.

Significance

This internal mandate was the foundational directive that compelled Amazon to build the highly decoupled and scalable infrastructure that would eventually be externalized as AWS services, including SQS. It fundamentally changed how Amazon itself built software.
