3 - Containerization

The “evolution” of the Virtualization is Containerization. It provides (kindaof) the same isolation as virtulization, but with fewer resources as containers runs as “ordinary” processes in the host system, with a careful designed security boundary that prevents interactions with other containers and with other processes in the same machine (and of course with the Operating System kernel).

This is based on Linux operating system, as containers leverage on technology that was created time ago for system administrators, that we will present. We will begin by describing the isolation of the containers, that serve the double purpose of ensuring safety and security (which is a very important aspect). Then, a brief Linux recap will introduce to the Container Fundamentals that show the functions of Linux that are used by Containers
