Comment on What's the deal with Docker?

I wouldn’t say that namespaces are virtualization either. Container don’t virtualize anything, namespaces are all inherited from the root namespaces and therefore completely visible from the host (with the right privileges). It’s just a completely different technology.

The word you’re all looking for is sandboxing. That’s what containers are - sandboxes. And while they a different approach to VMs they do rely on some similar principals.

I never said that it is a virtualization. Yet for easy understanding I named created namespaces “virtualized”. Here I mean “virtualized” = “isolated”. Systemd able to do that with every process btw.
Also, some “smart individuals” called comtainerization as type 3 hypervisors, that makes me laugh so hard :)
