> There's several use cases to virtualization Containers are not virtualisation. > So whatever you do with docker can also be done with type 1, 2 virtualization This statement is redundant. Whatever you do with docker can also be done with a Turing machine built using magic the gathering[1]. > There's plenty of junior programmers… And there are plenty of junior programmers who think containers = virtualisation :) 1. https://arxiv.org/abs/1904.09828 https://arxiv.org/abs/1904.09828

  > At least we do agree on one thing, there is one and only one subpar engineer among us. Indeed, the one who thinks containers are nothing but Docker. Or better yet, the one who cites a PDF from 2000 or an article from 2006, both before ec2 even launched, to say virtualization is synonymous with containers as if the meaning hasn’t shifted since then… Or, at the very least, the one who thinks “ssh apt-get install” is equivalent to a container image.

    Your reading comprehension might be quite bad >Indeed, the one who thinks containers are nothing but Docker. I just cited papers talking about jails, zones and chroot.. >to say virtualization is synonymous with containers I said containers are virtualization, not that virtualization is synonymous with containers. That is container ∈ virtualization, not container = virtualization. No offense but that's a highschool level reading comprehension error right there. >Or better yet, the one who cites a PDF from 2000 or an article from 2006, At least I cited stuff. Go ahead and submit something to wikipedia with sources if you think containers are no longer virtualization. Otherwise I'm out.
