What are the constraints? (e.g., "High availability," "Low latency," "Scalability to 10M DAU"). 2. Back-of-the-Envelope Estimation Before designing, you must understand the scale. Traffic: Queries per second (QPS). Storage: How much data will be generated over 5 years?

By establishing this flow early, you create a foundation that you can then optimize and "deep dive" into during the middle of the interview. 4. Scaling and Optimization What are the constraints
A great architect always asks, "What happens if this server dies?" Rylan Liu’s fundamentals stress the importance of to ensure the system remains resilient. The Value of the Rylan Liu Approach What are the constraints? (e.g.
