google-compute-engine redundancy how does it handle equipment failure?

jclerc asked:

what happens to my virtual instance in the case of a hardware failure of the google compute-engine?
Does the compute-engine auto migrate like it does when maintenance is performed?

My answer:

Google states that in case of hardware failure, your VM will also be migrated if possible, or restarted on a new host if migration is not possible.

Live migration keeps your instances running during:

  • Failed hardware such as memory, CPU, network interface cards, disks, power, and so on. This is done on a best-effort basis; if a hardware fails completely or otherwise prevents live migration, the VM crashes and restarts automatically and a hostError is logged.
