Motivation: I was tired of seeing VM vs Docker comparison explained by stacked rectangular boxes to introduce containerization concept. 1) The cover of the presentation hints some Docker features in Frozen (movie) theme: Docker can run frozen environments inside lightweight boxes isolated from your host machine. When you have many containers running, it becomes a "kingdom of isolation". So Docker basically "lets you run". It is a kingdom of isolation, and looks like you are coding. Let it run, let it run, I can't debug it anymore. 2) I used a concrete buildings vs spartan container houses analogy to explain the differences between VMs and containers. I came up with real-estate commercials, highlighting powerful aspects of both. Finally, I briefly introduce how "science-oriented" containers are different than the "market-oriented" ones. I have another presentation drilling down on this: https://zenodo.org/record/3625531#.XirCpFNKhsM
