Exoscale Scalable Kubernetes Service vs k0s

Exoscale Scalable Kubernetes Service (SKS) is a managed Kubernetes service for deploying, scaling and hosting containerized applications in Europe. It is available through web and APIs, with a free Starter Cluster and a Pro Cluster billed hourly; the Pro price is not shown as a numeric amount. Exoscale operates the control plane and provides upgrades, and says fully managed clusters can start in less than one minute. Starter includes a managed control plane, CLI, API, Terraform integration and automatic control-plane patch upgrades. Pro adds a highly available control plane, etcd backups, a 99.95% SLA and Karpenter autoscaling. Network Load Balancers handle ingress, while the CSI driver attaches block or object storage for stateful workloads. Authentication, network policies, role-based access and Kubernetes Audit provide control and visibility. Every release passes CNCF conformance tests. SKS is vanilla Kubernetes, so monitoring, GitOps and security tools are not installed by default. Customers receive ticket support, with paid plans offering faster responses and additional coverage.

k0s is a free, self-hosted Kubernetes distribution for deploying workloads across public and private clouds, on-premises systems, bare metal, edge locations, and IoT environments. It comes as a single binary and needs no host operating-system components beyond the kernel. The project describes it as CNCF-certified Kubernetes and lists support for x86-64, ARM64, ARMv7, and RISC-V. Installation options include single-node, multi-node, air-gapped, and Docker methods. The k0sctl tool supports cluster lifecycle tasks such as upgrades and backup and restore. Kube-Router is the default networking option; custom CNI plugins are supported, with Calico listed as a preconfigured alternative. Datastore choices include etcd, SQLite, MySQL, and PostgreSQL. Listed security features include kube-bench, RBAC, network policies, control plane isolation, and OpenID provider support. Minimum requirements are 1 vCPU and 1 GB RAM. The project aims to keep the base versatile by limiting bundled add-ons such as ingress, service meshes, and storage. Mirantis offers support services and subscriptions.
