web - Switching between a Vps/Dedi to a Cloud service (Like AWS/Google) -

im planning host app on vps or dedi @ same time want security if there downtime vps. there way can host app on dedi , whenever there outage of sort dedi cloud takes on , there no outage.

it looks want call "cloud vps" - virtual machine backed high-availability system, making them more resilient hardware outages. vms backed not openvz/kvm/xen (sadly, many of falsely advertized "cloud"), backed system of shared storage in case physical machine vm running on crashes, worst case reboots afterwards on physical machine, , best case don't notice because gets migrated live. example, i've used such service based on cloudstack.
