Answer
Eviction removes Pods for node stability; preemption removes Pods for priority scheduling.
Quick Answer
Node pressure eviction: kubelet proactively evicts Pods because the node is running low on memory or disk — it removes the lowest-priority Pods to keep the node healthy. Preemption: the scheduler evicts lower-priority Pods on a node to make room for a higher-priority Pod that couldn't fit. Eviction is reactive; preemption is scheduled.
