You are paying for the cluster you requested, not the one you use, and the gap is enormous. This whitepaper shows where the waste lives and the proven levers that recover 30 to 45% of cluster spend, permanently.
Developers set requests high to avoid throttling, the cluster runs at roughly 13% CPU utilization, and 83% of container spend goes to idle resources nobody owns.
A system that keeps utilization high by default, through rightsizing, autoscaling, bin-packing, spot, and quotas, recovers the waste and stops it from creeping back.
Most oversized-request waste, the 29% bucket, comes from pods asking for far more CPU and memory than they touch.
Overprovisioned infrastructure is the larger 54% bucket: too many nodes, or nodes too large, for what runs on them.
Lack of ownership is cited by 45% of practitioners as a top cost driver.
Requests are set by guesswork, there is no per-team visibility, and utilization sits in the low teens.
Deploy OpenCost or Kubecost so spend is attributed per namespace and team.
Rightsizing and the Vertical Pod Autoscaler bring requests down to observed usage, while the Horizontal Pod Autoscaler scales pod count to demand.
Node autoscaling, bin-packing, spot capacity, and namespace quotas keep utilization high automatically.
