I am learning Docker and I have searched the differences between Virtualization and Containerization. I understand everything clearly except one thing. How do we say that virtualization brings abstraction to hardware and Containerization brings abstraction to operating system? What is the idea behind this abstraction classification? Can anybody explain me the reason for classifying abstraction level like that for both type?

Containers are ordinary linux processes, check [this definition](https://twitter.com/jpetazzo/status/1047179436959956992): *"Containers are processes, born from tarballs, anchored to namespaces, controlled by cgroups"*. – tgogos Jul 26 '19 at 09:29

1I dont ask for the differences and silimarities between these concepts. I only ask for what reason we use these abstraction levels. – starrystar Jul 26 '19 at 11:18
