We keep saying "just add more servers." This post is about the part nobody explains when they say that: how a request actually finds its way to one of those servers, and how the traffic gets spread so no single machine drowns. It's the plumbing of every scalable system, and understanding it removes a lot of hand-waving.

This is part three of my system design fundamentals series, following the posts on scaling and on estimation.
