Ask HN: Where Are All the Sysadmins?

Been genuinely trying to hire someone competent that can deliver/manage HA solutions on-prem based on open source software, for more than 6 months now but with little success.

Someone that knows Proxmox, nginx, haproxy, zfs, mysql/mariadb clusters, Cisco (vPC ), all the required components to run an app locally and provide HA.

I know all these myself but I need to offload some of the tasks.

Is this too much or too old of a stack ? Has everyone really moved over to the cloud ?

(Note: offered salary 135k, in Canada, remote).
