Exoscale Scalable Kubernetes Service vs K3s

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.

K3s is a certified, lightweight Kubernetes distribution for IoT and edge computing. It runs self-hosted on Linux and is released for x86_64, ARMv7, and ARM64. The distribution arrives as one binary or a minimal container image; the site describes the binary as under 70 MB, while documentation says under 100 MB. Documented uses include edge systems, homelabs, IoT, continuous integration, development, ARM single-board computers, air-gapped environments, and embedded Kubernetes. SQLite is the default datastore, with etcd, MySQL, and Postgres available. K3s packages containerd or cri-dockerd, Flannel, CoreDNS, Traefik, ServiceLB, Kube-router, local-path-provisioner, and Spegel. High-availability deployments can use embedded storage or external MySQL, PostgreSQL, or etcd. Air-gapped installation supports private registries, manually deployed images, or an embedded registry mirror. Security guidance includes hardening and CIS self-assessment material. Automated Kubernetes-native upgrades use Rancher’s system-upgrade-controller.
