What's to Search for in a VM Provider When Increased Resiliency is Sought for But not Necessarily HA Compliance?

I am lost on how to search for a VM Provider beyond a few I found that boasts increased resiliency is commanded but not "total HA"?

My situation is as follows...

I am deaf and blind individual thus it's impossible for me to say set an alert say like PushOver to alert me while I am asleep since literally cannot hear a thing while sleeping. Since my hearing is in a such an impaired state (hence why I am deaf and blind since my sight is as well). Thus I am really looking for a provider who can simply auto migrate and reboot the VM onto a healthy node. Instead of being concerned of leaving my users without service for hours on end should the host node fails in say 3 in the morning.

May someone help me this sorta of thing out? Cause as I said I don't know how to search for a "in between" option between your usual Vultr, Linode, etc options to a "true HA" provider.

Thanks very much in advance!
