Sections of a system design document
- Overview, goals and non-goals: What are we building, and what are we not building?
- Requirements: What must it do, and how fast, big and reliable must it be?
- Architecture: What are the components and how do they talk to each other?
- Data model and storage: What data do we keep, where, and how is it accessed?
- APIs and interfaces: What do clients and other services call?
- Scaling and reliability: How does it handle growth, failures and peaks?
- Security and privacy: Who can access what, and how is data protected?
- Alternatives and risks: What else did we consider, and what could go wrong?
- Rollout and monitoring: How do we ship it safely and know it works?
What to give it for a useful draft
- The problem and who uses the system.
- Expected scale: users, requests per second, data size.
- Your stack and any hard constraints (cloud, budget, latency, compliance).
- The decisions you have already made, so it does not argue with them.
- Review every number and choice: it is a first draft for your team, not a final design.
