HA is overrated, i'd much rather go for a low mean time to repair.
Backups, reinstall, ansible playbook is my way to go if hardware fails, which is quite rare to be honest. HA goes beyond hardware in terms of "electricity, internet connection, storage, location etc.., IMO people quite often underestimate what it means to have real HA --> second location with identical setup to shift workload or even have active-active instead of active-passive.
i have an intel nuc as plain debian server with containers on it.
2 raspberry pi's(act as loadbalancers with traefik and authelia on top) and a hetzner vm all connected through wireguard.
All is configured via ansible and i rely on LE certificates to connect via https or directly via wireguard vpn to http if i want it only exposed via vpn.
encrypted backups are copied via wireguard to an offsite storage box.
full down to back online if hardware is not damaged is less than 15 min.
it is very easy to do and rock solid, unattend-upgrades does the trick.
i tried almost every combination and even though i am a k8s user from version 1.2 onwoards the complexity for k8s at home or even vsphere is too much for me vs. this super simple and stable configuration i now have.
