Ryan I haven’t seen any proposals/implementations from Mesos/Swarm (but I am not following Mesos and Swam community very close these days). But Kubernetes 1.1 has pod autoscaling (https://github.com/kubernetes/kubernetes/blob/master/docs/design/horizontal-pod-autoscaler.md), which should cover containers auto-scaling. Also there is PR for cluster auto-scaling (https://github.com/kubernetes/kubernetes/pull/15304), which has implementation for GCE, but OpenStack support can be added as well.

There was also a Magnum design session to discuss this same topics. The use cases are similar to what you describe. Because the subject is complex, there are many moving parts, and multiple teams/projects are involved, one outcome of the design session is that we will write a spec on autoscaling containers and cluster. A patch should be coming soon, so it would be great to have your input on the spec.

He likes the aspect of nova-docker that allows you to scale (essentially) infinitely almost instantly, assuming you are using a large pool of compute hosts. In the case of Magnum, if I'm a container user, I don't want to be paying for a ton of vms that just sit idle, but I also want to have enough vms to handle my scale when I infrequently need it. But above all, when I need scale, I don't want to suddenly have to go boot vms and wait for them to start up when I really need it. I saw [1] which discusses container scaling, but I'm thinking we can take this one step further. If I don't want to pay for a lot of vms when I'm not using them, could I set up an autoscale policy that allows my cluster to expand when my container concentration gets too high on my existing cluster? It's kind of a case of nested autoscaling. The containers are scaled based on request demand, and the cluster vms are scaled based on container count. I'm unsure of the details of Senlin, but at least looking at Heat autoscaling [2], this would not be very hard to add to the Magnum templates, and we would forward those on through the bay API. (I figure we would do this through the bay, not baymodel, because I can see similar clusters that would want to be scaled differently). Let me know if I'm totally crazy or if this is a good idea (or if you guys have already talked about this before). I would be interested in your feedback.
