## AI overview

This article explains how Kubernetes PodDisruptionBudgets protect application availability during voluntary disruptions such as node drains, autoscaler consolidation, and pod migration. It describes the risks of missing PDB definitions, explains how PDBs limit simultaneous pod unavailability, and outlines how to identify deployments without them and test their behavior.
