Summary
Engineer’s Codex breakdown of Instagram’s early tech stack (2010-2011, 0 to 14 million users, 3 engineers). Three guiding principles: keep things simple, don’t reinvent the wheel, use proven technologies. Stack: AWS EC2/Ubuntu, Django/Python/Gunicorn, Amazon ELB + NGINX, PostgreSQL, Redis, Gearman.
工程師密碼本對 Instagram 早期技術棧的分析（2010-2011，0 到 1400 萬用戶，3 名工程師）。三個指導原則：保持簡單、不重複造輪子、使用成熟技術。棧：AWS EC2/Ubuntu、Django/Python/Gunicorn、Amazon ELB + NGINX、PostgreSQL、Redis、Gearman。
Key Points
- 3 guiding principles: keep it simple, don’t reinvent the wheel, use proven/solid technologies
- Frontend: iOS app (Objective-C), deployed October 2010
- Load balancing: Amazon ELB + 3 NGINX instances (swap out unhealthy instances)
- App servers: Django + Gunicorn on 25+ Amazon High-CPU Extra-Large; stateless → add machines to scale
- Deployments: Fabric (parallel command execution across instances) — deploy in seconds
- Data storage: PostgreSQL (primary), Redis (caching/sessions), Gearman (async task queue)
Insights
The most striking lesson is what’s not there: no custom distributed systems, no exotic databases, no microservices — just the most boring, proven stack available in 2010. This validates the “complexity is a symptom of bad design” thesis from system design literature. The 3-engineer constraint forced ruthless simplicity that paid enormous dividends. Instagram’s success came not from technical novelty but from product insight combined with an extremely pragmatic engineering culture. The stateless application server design (add more machines to scale) is the key architectural decision that enabled rapid horizontal scaling.
