You're right, having only one person on call for a managed cluster doesn't make a lot of sense. We should probably have planned with at least 2 people for a managed cluster too to cover 24/7/365 operations.

I think our thought process here is that developers are also involved in on call support for the service availability and the k8s cluster availability is mostly managed by the provider, but the cluster can still fail even if the control plane is managed.

Self managed cluster needs networking, some kind of persistent volume storage and the nodes themselves need to be somewhat maintained.

I think you could get one person to be on-call for all those things, personally. But then I think that person should not be on-call for application support (IE; not the things running inside k8s, they would be the person the on-call application developer/administrator would call if they couldn’t debug issues with networking, for instance).
