Kubernetes Cost Optimization

Reduce Kubernetes infrastructure costs by 40–60% through cluster rightsizing, Spot/Preemptible node strategies, workload resource tuning, and pod-level cost attribution across EKS, AKS, and GKE.

Why Businesses Need This Service

Kubernetes clusters are one of the most expensive and most inefficiently used components of cloud infrastructure. Node pools are sized for peak load, pod resource requests are set too high by developers who don't want to be paged at 2am, and there is no visibility into which teams or workloads are responsible for which costs. Kubernetes Cost Optimization brings the same financial discipline to container infrastructure that FinOps brings to cloud infrastructure overall.

Key Capabilities

Comprehensive capabilities to address your cloud needs

Node group and node pool rightsizing based on actual workload resource utilisation

Spot/Preemptible Instance and Spot Node Pool configuration for non-critical workloads

Pod resource request and limit tuning using Vertical Pod Autoscaler (VPA) recommendations

Horizontal Pod Autoscaler (HPA) and KEDA configuration for efficient scaling

Kubecost deployment for namespace, team, and workload-level cost attribution

Cluster consolidation — reducing cluster count while maintaining isolation requirements

Our Implementation Process

A systematic approach that ensures timely delivery and exceeds expectations

Step 1

Cluster Cost Audit

Deploy Kubecost, analyse cost allocation by namespace and workload, identify overprovisioned node groups and pods, and establish cost baseline.

Step 2

Resource Rightsizing

Deploy Goldilocks VPA advisor, analyse resource request recommendations, tune pod requests and limits workload by workload, and validate application stability.

Step 3

Node Optimisation

Configure Spot/Preemptible Node Pools for non-critical workloads, implement node affinity rules, deploy Karpenter for dynamic provisioning, and right-size on-demand node groups for critical workloads.

Step 4

Autoscaling Enhancement

Review and tune HPA configurations, implement KEDA for event-driven workloads, and configure cluster autoscaler or Karpenter policies to scale down aggressively outside business hours.

Step 5

Cost Attribution & Governance

Implement team-level cost attribution with Kubecost, configure resource quotas per namespace, establish monthly cost review process, and integrate cost metrics into engineering dashboards.

Example Success Story

See how we've helped businesses achieve success with cloud solutions

Client Challenge

A SaaS platform spent $420,000/year on EKS infrastructure. Clusters ran at 28% average utilisation, all workloads ran on on-demand nodes, pod resource requests were set to developer estimates from 2 years ago, and there was no visibility into which teams drove which costs.

Cloud Solution Implemented

We deployed Kubecost for cost attribution, used Goldilocks to generate VPA recommendations and tuned pod requests across 145 deployments, implemented Spot Node Pools covering 70% of the workload, deployed Karpenter replacing the Cluster Autoscaler, and set up namespace-level cost quotas and dashboards.

Business Results

$195,000/year reduction (46%) in EKS costs

Spot Node Pool coverage at 70% saving $140,000/year

Pod resource waste reduced by 38% through VPA tuning

Cluster utilisation improved from 28% to 64%

Cost attribution by team and product implemented

Frequently Asked Questions

Common questions about Kubernetes Cost Optimization

Kubecost is an open-source and commercial tool that provides real-time cost visibility and attribution for Kubernetes clusters. It shows cost per namespace, deployment, pod, and label — enabling teams to understand their infrastructure spend without relying on cloud billing exports alone.
