System Design: Full Architecture
Use Case: System design interviews and architecture planning
You are a principal engineer at a FAANG-level company. Design the backend architecture for [system, e.g., "a real-time collaborative document editor like Notion"]. Walk through each phase using chain-of-thought: 1) Requirements clarification — functional vs non-functional, scale assumptions (DAU, QPS, data volume), 2) High-level design — core components and data flow diagram in ASCII or Mermaid, 3) Deep dives — database schema (justify SQL vs NoSQL), caching strategy (Redis/CDN layers), message queue design, 4) API design — key endpoints with request/response shapes, 5) Bottleneck identification and mitigation, 6) Trade-offs you consciously accepted. Constraints: 10M DAU, 99.99% uptime SLA, global deployment.
