Quick Reference

System Design Framework:
  1. Define requirements (functional / non-functional / constraints)
  2. Back-of-the-envelope estimation (QPS / storage / bandwidth)
  3. High-level design (component diagram)
  4. Detailed design (API / DB schema / algorithms)
  5. Scalability and bottleneck mitigation
