what actually limits scale at each layer, and how teams address it.
scale problems only show up when people are actually using your system. most software never gets here.
they are also genuinely hard. a system that handled a hundred requests a second does not automatically handle ten thousand. the bottlenecks are different, the failure modes are different, and the fixes are often irreversible architectural decisions made under pressure.
this section is about understanding scale before you are in that situation. not so you can prematurely solve problems you do not have, but so that when growth arrives, you have a framework for responding to it.
