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.
