Docker, containers, rkt, kubernetes, the Open Container Project, CoreOS, and RancherOS are some of the new buzzwords in cloud. If you've read any articles on them you may have been left thinking this is the new hot technology space but you're unsure of how to leverage it in your own environments. You may even still be wondering how this, in a practical sense, is different from working with virtual machines or the other platforms you've been using. In this session we'll start with an introduction into containers. We'll look where we are going in computing and how containers can be useful in ways virtual machines can't. From there we'll look at ways you can use containers and Docker in your environments today. We'll round out our time by looking at what's being built with container technology that can help you.
