If you are a small operation and trying to self host k3s or k8s or any number of out of the box installations that are probably at least as complex as docker compose swarms, for any non trivial production case, presents similar problems in monitoring and availability as ones you’d get with off the shelf cloud provider managed services, except the managed solutions come without the pain in the ass. Except you don’t have a control plane.

I have managed custom server clusters in a self hosted situation. the problems are hard, but if you’re small, why would you reach for such a solution in the first place? you’d be better off paying for a managed service. What situation forces so many people to reach to self hosted kubernetes?

Price. Data sovereignty. Legal. All are valid reasons to self-host
