Cheapest Cloud Servers for Kubernetes (k8s & k3s)

Find the cheapest cloud instances for Kubernetes control planes and worker nodes. Compare compute pricing across Hetzner, DigitalOcean, AWS, and Scaleway for maximum cluster efficiency.

概要とクイックアンサー

Cost-optimized cloud compute instances for building budget-friendly Kubernetes clusters.

アーキテクチャ＆デプロイガイド

For production Kubernetes clusters, separate your control plane (minimum 2 vCPU, 4GB RAM) from worker nodes (minimum 4 vCPU, 8GB RAM). Utilizing Hetzner or Scaleway for self-managed or managed k8s reduces cluster costs by up to 75% compared to AWS EKS or Azure AKS.

推奨ハードウェアスペック: 4 vCPU · 8 GiB RAM

コスト最適化戦略

  • ✓Use lightweight distributions like k3s or Talos Linux to minimize system resource overhead.
  • ✓Mix On-Demand nodes for the control plane and stateful apps with Spot/Preemptible nodes for stateless workers.
  • ✓Deploy an autoscaler (like Cluster Autoscaler or Karpenter) to scale down idle node capacity during off-peak hours.

よくある質問

クラウドコンピュートの価格とインフラに関する一般的な疑問への直接の回答。

What is the cheapest way to run a production Kubernetes cluster in the cloud? ▼

Using Hetzner Cloud with Hetzner Managed Kubernetes (or self-hosted k3s) provides a full 3-node cluster (4 vCPU, 8GB RAM each) for under €35 to €40 per month, compared to $200+/month on AWS EKS or GCP GKE.

Can you use Spot instances as Kubernetes worker nodes? ▼

Yes, Kubernetes handles pod rescheduling automatically when nodes are terminated. By pairing Spot worker nodes with graceful pod disruption budgets (PDBs), you can run stateless workloads for 70-90% less cost.
