## What it is
Descheduler is a Kubernetes component that evicts pods whose original scheduling decisions no longer make sense, such as pods on under- or over-utilized nodes or after node taints, labels, or affinity changes. It relies on the default kube-scheduler to reschedule the evicted pods onto more appropriate nodes.

## Use cases
- rebalance pods off overutilized kubernetes nodes
- evict pods that violate updated node taints or affinity rules
- move pods to newly added nodes in a cluster
- clean up pods stranded after node failures
- periodically reschedule pods for better cluster utilization

## When to choose
- you run a dynamic kubernetes cluster where node utilization drifts over time
- you need policy-driven pod eviction to complement kube-scheduler
- you want a kubernetes-sigs maintained tool with helm charts and versioned releases

## When to avoid
- you need a scheduler that places pods directly rather than evicting them
- you cannot tolerate pod disruption from evictions
- you are not running kubernetes
