Containers affirmation Resource

I would like to know if there is any resources, books, papers or journals sustaining this affirmation. Is there a way to know who "owns" the affirmation?

"Containers
Most times, to ease the understanding of the concept, a container is compared to a regular Virtual Machine - which is a result of full virtualization. A container, however, is the product of several OS-level virtualization features of the Linux kernel used in conjunction to build a lightweight isolated environment. These environments provide secure runtimes for either simple scripts to full-sized web-servers. It is quite obvious why containers are compared to VMs: they have their own process trees, network interfaces, users, root, file systems, just to name a few reasons. There are quite a few differences as well, between VMs and containers: containers use the host kernel and are bound to boot the host OS only, and are processes running on the host system managed individually or in groups."
