Apache Mesos, Apache Aurora, Mesosphere, Marathon, the list of Linux container based enterprise software goes on and on.
Lots of people are interested in containers these days, and companies like Mesosphere have lept into the business of selling container based clouds to the enterprise who wants to run their own applications. Apache Aurora came about when Twitter made their own internal developed cloud software open source, and both use Apache Mesos to operate the cloud. Mesos runs containers, your own, or even Docker. I imagine they will support, or probably be part of the new open source container standard being hashed out right now.
You can have a private cloud, public cloud, or hybrid. New servers come online almost instantly, and things like auto-scaling and live migrations to distribute load are built in. This is fantastic technology.
