The Myth of Excess Capacity: A common theory suggests AWS emerged to monetize Amazon’s excess server capacity outside Q4. But this falls apart—what would Amazon do in peak season? Plus, DEC servers had 80% margins, making excess capacity unlikely in the first place.
The Tim O’Reilly Pitch: Another theory credits Tim O’Reilly for the AWS idea—doing business with thousands of companies without formal contracts. Amazon’s first API opened access to its entire product catalog, enabling revenue-sharing instead of traditional BD deals.
Andy Jassy’s Retention & Role Creation: When Amazon’s entire marketing department was disbanded, most executives left. However, Jeff Bezos personally retained Andy Jassy, creating a new role for him as Technical Assistant—a position that had never existed before. This role placed Jassy in Bezos’s inner circle, allowing him to influence Amazon’s long-term infrastructure strategy directly.
Service-Oriented Architecture (SOA): Instead of relying on program management (like Microsoft), Amazon made all internal data API-accessible from day one. Every service was built externally, formalized in Andy Jassy’s six-page memo advocating infrastructure externalization for speed and efficiency.
The Network Infrastructure Memo: Benjamin Black and his boss wrote an internal memo not just to optimize Amazon’s network but to sell infrastructure to third parties. Meanwhile, Chris Pinkham independently built AWS components in South Africa.
Core AWS Services: Amazon identified four key pillars for scalable development—Storage, Compute, Databases, and CDNs. They hired 57 top engineers (future CEOs of Tableau and Twilio) and launched services in order: S3 → EC2 → CloudFront → RDS.
Execution Over Ideation: AWS wasn’t a single stroke of genius but a sequence of micro-decisions. Andy Jassy’s relentless execution turned AWS into a dominant business unit.
AWS and the Shift in Software Development: Hackathons became viable because AWS provisioned infrastructure instantly. Netflix migrated to AWS, despite competing with Amazon in video streaming. Traditional enterprise players (IBM, Oracle, DEC) ran on 80% margins—AWS disrupted them with pay-per-use at 30% margins. IaaS (Infrastructure-as-a-Service) let companies adopt state-of-the-art hardware without waiting for refresh cycles.
Enterprise Database Lock-In: Moving enterprise databases is hard, making vendor lock-in inevitable. Amazon tackled this with Snowball & Snowmobile—secure physical storage devices avoiding internet transfers. Even with these, Amazon’s own migration from Oracle took 13 years, finishing in 2019.
AWS’s Edge in ML: AWS doesn’t need the best ML models—it wins because data stickiness ensures customers run ML where their data is stored.
AWS’s Biggest Failure: Data Warehousing: AWS should have dominated data warehousing, but instead, Snowflake became a $50B company—a major missed opportunity.
The Two-Pizza Team Problem: Amazon’s small, independent teams drove innovation but also flooded AWS with too many services, many of which are rarely used.
AWS’s Growing Profitability: Operating profit margins jumped from 19% to 30%, thanks to economies of scale. AWS generates more gross income than Amazon’s retail business, making it the company’s most profitable division.
Steve on why unconventional words work:
People forget that audiences want to be both informed and entertained.
Steve and Charlie Munger aligned on more ideas than one:
Decentralization & law enforcement: Centralized platforms can easily enforce laws—they control what actions are allowed and can ban or penalize users. Similarly governments can hold platform owners accountable for activity undertaken on their platform (telegram). Decentralized systems pose a challenge
