## AI overview

This blog explains how Kubernetes topology spread constraints distribute pods across failure domains such as availability zones, regions, and nodes. It covers their reliability benefits, configuration through spec.topologySpreadConstraints, and the main constraint fields and behaviors.

## Source excerpt

Topology spread constraints let you determine how Kubernetes spreads pod replicas across failure domains, such as availability zones and regions. This blog explains how they work, how to configure them, and how to scan for missing constraints.
