## TL;DR

Load balancing distributes traffic or workload across multiple backends to improve availability, performance, and fault tolerance. This repair removes popularity and vendor-ranking claims and cites vendor documentation directly.

## Core Explanation

Load balancers commonly combine backend pools, routing methods, and health checks. The operational goal is not just spreading traffic, but avoiding unhealthy or overloaded targets while preserving a stable entry point for clients.
