i have an intel nuc as plain debian server with containers on it.
2 raspberry pi&amp;#x27;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.&lt;p&gt;full down to back online if hardware is not damaged is less than 15 min.&lt;p&gt;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.</text></item></parent_chain><comment><author>xani_</author><text>&amp;gt; HA is overrated, i&amp;#x27;d much rather go for a low mean time to repair.&lt;p&gt;Those are almost entirely independent domains&lt;p&gt;the only point where they connect is that&lt;p&gt;&amp;gt; full down to back online if hardware is not damaged is less than 15 min.&lt;p&gt;automation makes both easier to deal with.&lt;p&gt;&amp;quot;Mean time to repair&amp;quot; is all fine if you don&amp;#x27;t have to drive 30 minutes to datacenter to swap out stuff.&lt;p&gt;Even if its cloudy cloud and you have backups, restores can take a lot of time.&lt;p&gt;Also you &lt;i&gt;will&lt;/i&gt; want HA when it&amp;#x27;s your internet gateway to die&lt;p&gt;There are also levels of implementation. Making fully redundant set of loadbalancers is relatively easy. But any stateful app is much, much harder. In case of applications active-passive type of setups are also much easier than full on active active redundancy, especially if app wasn&amp;#x27;t written for it.</text></comment>

HA is a good investment for things that are &amp;#x27;stateless&amp;#x27; -- eg: VIPs&amp;#x2F;LBs&lt;p&gt;Rebuilding existing systems (or adding new ones) is excellent, but sometimes life really gets simpler when you have one well-known&amp;#x2F;HA endpoint to use in a given context</text></comment>
