Resource request
A resource request is the CPU and memory a Kubernetes container says it needs, which the cluster reserves for it whether used or not; a limit is the most it may use. Requests decide how many workloads fit on each node. Why it matters: Requests set far above real usage leave you paying for reserved but idle capacity.
