At the time I worked through this course I had recently had a conversation with a friend who is heading up the programming department of a research lab. He told me how his company was using Docker and how it served their purposes better than simple virtual environments. It was in the pursuit of some current, industry-proven technology that I chose this course to familiarize myself with. I had been coming to see how useful VMs were, so it seemed like a good idea to learn about Docker.
