At the same time that we are sharing hardware resources, we are able to provide strong layers of isolation between VMs, because we need to make sure that access and permissions cannot bleed across VMs particularly in a cloud provider scenario, as that would spell disaster.

Application containers are the same idea, at a different level. Where VMs are all...
