I remember we were running 500 solaris zones and 5000 vmware VMs over 2 datacenters with 0 major outages over 4 years. I remember a (single) VM crashing and it was a really big deal (turned out it was a config issue, in retrospect a funny one although our (internal) client lost some data). And I remember we were in "crisis mode" for a couple weeks because of SAN storage issues but there was no client interruption of more than 1 minute over those 2 weeks. One of our client was running our app in a cross-datacenter cluster on bare metal with no interruption for over 20 years.

I'm not advocating for any of those specific solutions and given the choice I would probably use something else, but when I see that my previous CTO wanted kube for single-VM deployments, and a former architect collegue wanted kube for apps that were going to be used by 3 to 5 clients maximum (and in both cases to be run by very small and untrained teams), I think the kool aid has been more than drunk, and I'm now avoiding it like the plague.
