Containers and OpenStack
Now that we know what containers are, we can discuss how they are beginning to impact OpenStack, both in terms of architecture and workloads. First, we will discuss how containers are perfect for being run on OpenStack and how they can be operated in the tenant space using new and existing projects. Second, we will cover how several OpenStack distributions are using container technology to drive additional efficiency, resiliency, and high availability into the OpenStack control plane.

Why would anyone want to run Docker on OpenStack? First, OpenStack has built-in drivers for launching docker containers with the same method as VMs, using Nova. This driver has been around a long time and works very well. There's a lot to be said for having a single orchestration platform for containers, VMs, and bare metal. Even without launching the direct virtualization driver for Nova to create native Docker containers, users can simply provision VMs with images...
