Principles of Designing Scalable Systems
A good first chapter to start this part.
In Part 2, we collect a set of approaches rather than one “correct recipe”. Every system lives under its own constraints: SLA, budget, traffic shape, requirements for consistency, and the speed of change. Your job as an engineer is to understand which architectural tools to choose and why.
Why Understanding Multiple Design Approaches Matters
No universal blueprint
An approach that works great for a read-heavy API can be a poor fit for event-driven workflows or stateful systems.
Trade-offs are inevitable
Architectural decisions always reshape the balance between latency, availability, consistency, cost, and operational complexity.
The language of interviews and production
Being able to justify your approach matters both in system design interviews and in real architecture reviews within a team.
What’s Inside This Part
1. Architecture primitives
2. Adapting to system types
3. Interview practice and preparation
Suggested Learning Path
- Start with `Scalable Systems` to align on core architecture principles.
- Move to `Caching`, `Load Balancing`, and `Event-Driven` as the key building blocks.
- Reinforce the concepts with `System Types`, where different platform contexts are compared.
- Finish this part with the interview practice and troubleshooting chapters.
This part helps you go from “I know patterns” to “I can choose the right approach for the job”.
