What Actually Differs Between a Container and a VM — namespace, cgroup, and the Bill for Sharing a Kernel
Starts with why the explanation that a container is a lightweight VM breeds misunderstanding. A container is an ordinary Linux process whose view is masked by namespaces and whose resources are limited by cgroups, and it
