Overview

Containers vs. Virtual Machines

Container	VM
Does not contain OS in the container (each container must be based on the same OS)	Contains OS, so each virtual machine can run different OS-based applications
Boots up faster	Boost slower
Takes up less space	Takes up more space

As shown above, we actually want to combine the two like so.

Container vs. Images

You spawn instances of an image (the instances are the containers).
