We are DigitalOcean circa 2015 mature. Good enough for some very large customers, good enough for many developers, not some place I'd run pacemaker infrastructure.
Does anyone run pacemaker on non-baremetal? Can you even? I’m aware you’re just using it as an analogy/example, but was just wondering..
I did run some VRRP or CARP stuff (forget the specific tool/protocol - but that's kinda like pacemaker right?) in an immature OpenStack cloud once that didn't have a good LBaaS yet. It was a semi supported hack documented by the provider.
FWIW, I'm pretty sure OP was referring to literal pacemakers, as in, the things that keep people's hearts beating.
Where would you feel comfortable running pacemaker infra? Half-joking here.
