Virtualization and Docker

I use Virtualization and Docker to better utilize the computing power of my server. While Virtualization and Docker are similar in function, I originally had a lot of trouble trying to learn Docker by abstracting it in terms of Virtualization. Once I realized this I made the choice to just create a new "Object" in my head for Docker instead of trying to make it fit into virtualization. Also, both technologies can and should be used concurrently to get the most from a computer given the current software and hardware landscape.
