## AI overview

This tutorial explains how load balancers distribute requests across multiple servers using algorithms such as round robin and weighted round robin. It describes their simplicity, health-check behavior, and limitations when servers differ in capacity or handle long-running requests.

## Source excerpt

When your application runs on multiple servers, you need a way to distribute incoming requests across them.
