Kubernetes Cost Optimization: FinOps for Platform Teams

Quick Wins

Set requests from actual P95 usage; enable cluster autoscaler; delete orphaned PVCs and load balancers.

Implementation Checklist for 2026

When rolling out changes related to Kubernetes Cost Optimization, start with a two-week technical spike on the riskiest integration point. Document assumptions, measure baseline metrics, and define rollback before touching production traffic.

Give someone ownership of the cluster bill with the authority to act on it. Visibility without authority produces excellent dashboards and unchanged spending.

• Write a one-page architecture decision record (ADR) before sprint one
• Define success metrics tied to business outcomes, not output
• Run performance and security checks in CI, not at the end
• Plan training for support and sales before launch day

Common Mistakes We See in Client Audits

The recurring failure is optimising node cost while ignoring requests and limits. Over-requested pods reserve capacity nobody uses, and no amount of instance shopping recovers it.

The costly mistake is tuning before measuring. Get per-namespace and per-team attribution working first, because until costs have owners, nobody has a reason to reduce them.
