Jeff Bezos's Mandate

Jeff Bezos issues a company-wide mandate stating that all teams must expose their data and functionality through service interfaces, and all communication must happen via these interfaces. This forces Amazon.com to re-architect its monolithic infrastructure into a service-oriented architecture.

Significance

This internal directive, initially aimed at fixing Amazon's internal operational inefficiencies, inadvertently created the modular, API-driven foundation that would later become AWS. It cultivated the engineering mindset necessary for a public cloud.
