Capstone - From 100 to 1,000,000 Requests per Second

1. How This Capstone Works

Five lessons introduced five patterns that share one discipline, capacity follows the bottleneck, and this capstone grows one service across four orders of magnitude while asking the same three questions at every stage. Which part currently limits throughput, which inexpensive tool can move that limit, and which parts should remain unchanged?

At each stage, stop at the "pause and decide" box and identify the constraint before selecting a pattern. Interviewers often repeat this exercise by increasing traffic tenfold and asking what fails next
