Docker nutzt auf Linux-Servern sehr stark den Linux-Kernel, zum Beispiel die Features „namespaces“ und „cgroups“. Die Technik wird dementsprechend auch in Windows Server 2016 übernommen.

cgroups (abbreviated from control groups) is a Linux kernel feature that limits, accounts for, and isolates the resource usage (CPU, memory, disk I/O, network, etc.) of a collection of processes.

Namespaces are the important building block of Containers which isolates the applications from each other within single or multiple container' scope. When multiple processes / services are being run on multiple containers (on a single host system) then such isolation is a necessity from security and stability standpoints. A very essential command "docker run" itself creates the set of namespaces and controls the containers.
