Cut Costs, Not Performance: Implement Kubernetes Cost Optimization Strategies
summary
Three concrete tactics reduce Kubernetes cloud spend with measurable results: cluster resizing (remove nodes when overall CPU and memory sit ~25–45%), instance right‑sizing (swap M5x.large → R5.large across 100 nodes saved ≈$4,000/month) and replacing ondemand with spot instances (50–70% savings for stateless or batch workloads). Needs 1–6 months of metrics, correct requests/limits, PDBs and autoscaling. Watch for bulky monolith pods, regional instance availability and instant spot eviction. Also enforce cleanup of orphaned volumes, cheaper storage classes, namespace chargeback and ephemeral environment automation.
