Amazon: The API Mandate — How AWS Was Born
How a single internal memo from Jeff Bezos accidentally created the world's most profitable cloud business.
The challenge
In 2002, Amazon's internal teams built systems that couldn't talk to each other. Every team had different data formats, different protocols, and rebuilding the same infrastructure repeatedly. Amazon was growing fast but internal complexity was slowing everything down.
The strategy
Bezos sent an infamous memo with 6 rules: all teams must expose data through service interfaces, teams must communicate through these interfaces, no other forms of interprocess communication allowed, it doesn't matter what technology they use, all service interfaces must be designed to be externalizable, and anyone who doesn't do this will be fired.
