K3s by Rancher
Pros
- + Free, open source, CNCF sandbox project with full Kubernetes API conformance
- + Single sub-70MB binary with bundled containerd, Flannel, CoreDNS and Traefik — cluster up in under a minute
- + Documented hardware minimums and database sizing guides instead of vague marketing claims
- + Runs on x86_64, ARMv7 and ARM64 — from Raspberry Pi agents to large cloud servers
- + Flexible datastores: embedded SQLite or etcd for HA, plus MySQL, PostgreSQL and MariaDB
Cons
- - Stripped component set — some upstream Kubernetes features and in-tree plugins are absent
- - Multi-cluster management is a Rancher/SUSE Rancher Prime feature, not part of K3s
- - You own operations: upgrades, datastore integrity, network policy and security hardening
- - Enterprise support and long-term maintenance require buying into the SUSE Rancher stack
- - Community-scale ecosystem — GitHub issues and chat, no vendor-neutral enterprise backing
OVHcloud Managed Kubernetes
Pros
- + Permanently free managed control plane on the Free plan (up to 100 nodes)
- + Standard plan adds dedicated multi-AZ control plane for $0.099/hour per cluster
- + Official Terraform/Pulumi support, autoscaling, OIDC, vRack private networking
- + EU data residency with regions in France, Germany, UK and Poland
- + $200 Public Cloud trial credit covers roughly a month of real worker nodes
Cons
- - Free plan SLA is 99.5% with no service credits; Standard 99.99% promised only after beta
- - Control panel is dense and less polished than GKE or DigitalOcean
- - Ticket-based support on standard tiers; no multi-cluster management in-product
- - etcd quota (400 MiB free / 8 GiB standard) limits CRD-heavy operator usage
