Correct, but at least at the moment we aren't using auto-resizing, and I've never seen nodes get removed without us manually taking some action (e.g. upgrading Kubernetes releases or similar). Are there automated events that can delete a VM and remove it, without us having done something? Certainly I've observed machines rebooting, but that also preserves dedicated IPs. I can live with having to take some manual configuration action periodically, if we are changing something with our cluster, but I would like to know if there is something I've overlooked. Thanks!
