Kubernetes Cost Optimization: Rightsizing, Spot, and FinOps

Cloud-native cost is a top concern. Here’s how to optimize Kubernetes spend without hurting reliability.

1. Rightsizing Requests and Limits #

Set requests to what you need on average; limits to a safe ceiling. Over-requesting wastes money; under-requesting causes throttling or OOMKills.

yaml.yaml

resources:
  requests:
    memory: "256Mi"
    cpu: "100m"
  limits:
    memory: "512Mi"
    cpu: "500m"

Use VPA (Vertical Pod Autoscaler) or similar to tune over time.

2. Spot / Preemptible Nodes #

Run batch and fault-tolerant workloads on spot instances. Use node affinity and tolerations so critical workloads stay on on-demand.

3. FinOps Practices #

Tag namespaces and labels for chargeback and showback.
Set budgets and alerts so teams see cost before it spikes.
Review idle resources (unused PVs, load balancers, old images) regularly.

Best practice: treat cost as a non-functional requirement and review it in sprint retros.
