IONOS vs AWS (EKS): Kubernetes Cost Comparison (2026)
IONOS is 3% cheaper than AWS (EKS) for a 3-node Kubernetes cluster (€96 vs €99/mo)
At the cluster level, IONOS runs 3% cheaper, roughly €3/mo less than its competitor. At 6 nodes, AWS (EKS) actually becomes cheaper — worth considering if you plan to scale to HA. AWS (EKS) delivers ~6× the storage IOPS, which matters for write-heavy workloads like etcd or database operators. Control plane costs differ: IONOS includes it free; AWS (EKS) adds €73/mo. Choose IONOS for cost-efficient Kubernetes on a budget; choose AWS (EKS) for IOPS-intensive stateful applications.
Moving off AWS (EKS) could save ~€3/mo on a 3-node cluster.
