Seems perfectly straightforward. If you believe containers give you the level of isolation that VMs would, then you have fundamental misunderstandings of the technology which in a sane organisation would preclude you from operating important systems.
No your comment is anything but straightforward. In fact its grammatically incorrect to the point of being incoherent and incomprehensible. Maybe you should re-read what you wrote? It's bizarre to think that anyone would read that and think it was articulate.
Nowhere did I state that or even remotely suggest that containers give you the level of isolation that VMs would. My comment was refuting the OPs suggestion that "configuration management" was relevant to the article. Maybe you should go back and re-read the thread.
