What problem it solves

System design is a broad topic with many resources scattered throughout the web, making it difficult to find an organized learning path. Candidates also need a structured way to practice common design questions and compare their results with sample discussions, code, and diagrams.

Key features

• Structured system design topics — The guide organizes core topics and explains their use, benefits, limitations, and trade-offs. Topics include scalability, consistency, availability, caching, databases, asynchronism, communication, and security.

Who it may suit

This guide may suit engineers learning to design systems at scale and candidates preparing for technical system design interviews.

Topics to discuss

• Which system design topics should learners prioritize for a short, medium, or long preparation timeline?

• How can the interview workflow be improved for unfamiliar design questions?

• Which additional practice problems or learning resources would be most useful to the community?
