If that's the case, why do my VMs in public clouds constantly go down for hardware maintenance? We've definitely regressed despite the buzzwords and hype.

  Most of the "hardware maintainance" is defragmenting the workload so that the VMs run in fewer physical machines to retire racks of old hardware. Some load balancing too.

    Or an endless line of Spectre/Meltdown patches needing the hosts to reboot in order to get this weeks firmware into the intel CPUs.

      This is what I was getting at. When Sun had issues with CPUs, they sent you new CPU boards and you could hot swap them live without downtime

        That was indeed cool, but it also belongs to the "pet" phase of computing and this is the "cattle" age.

          Not really. It was done at scale, too. Hotmail replaced all of the faulty CPUs live.
