Managed databases should be coming soon to Linode: https://www.linode.com/products/databases/

Great! If they let me have K8S clusters with 0 nodes I'll move back there.

I’m not sure I understand that use case? What is the point of a cluster without nodes.

I'm a K8S newbie, and running on DO, so take it with a grain of salt: I have a couple of `CronJob`s, running twice a day, that would run way faster on better hardware, but as far as I can tell, it's impossible to do so on DO unless I keep a cluster with a minimum of 1 node online all the time.
