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.
Résumé Exécutif et Réponse Rapide
Cost-optimized cloud compute instances for building budget-friendly Kubernetes clusters.
Guide d'Architecture et de Déploiement
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.
Stratégies d'Optimisation des Coûts
- ✓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.

Foire Aux Questions
Réponses directes aux questions fréquentes sur la tarification et l'infrastructure cloud compute.
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.
