In this chapter, we explored the alternative platforms on which we can run Docker Swarm clusters. We worked with the newest Docker tools--Docker for AWS and Docker for Azure--and we used them to demonstrate how to install Swarm in a new fashion. After introducing Docker Datacenter, we moved to the private cloud part. We worked on OpenStack, showing how to run Docker hosts on it, how to install OpenStack Magnum, and how to create Swarm objects on it. We've almost finished our travel.

The next and last chapter will sketch the future of Docker orchestration.
