Kubernetes cost optimization on EKS: a 62% reduction
Spot instances, Karpenter, right-sizing, and the governance patterns that keep savings sticky month over month.
An EKS cluster that cost $58k/month now runs at $22k/month with the same workload, the same SLA, and the same on-call rotation. The journey was less about clever tooling and more about discipline.
We share the order of operations: tag everything, right-size before you optimize, then introduce Karpenter for node churn, then spot for batch, then reservations for the steady-state baseline. We also share the FinOps review cadence we now run for every cloud engagement, and the dashboards that keep engineering honest.
