Mastering the System Design Methodology

links:none on file
slides:none on file

Claims a repeatable system‑design methodology centered on C4 modeling, empathy-driven requirements and lightweight tooling (Miro/mirrorboard, ChatGPT, AWS/Route53, Redis). Shows a working example — a car‑checkout site shipped for Tesla in 2014 — and quantifies scale: 1B requests/day ≈ 12k RPS, Redis ~300GB per node, autoscaling pods take autoscaling has 3–5 minute start latency, and Amazon loses ~$1.5B for a 1s latency increase. Covers concrete patterns: read replicas, caching, shard strategies (shuffle sharding), capacity math, and when to split by function.
