Hello, we are considering adopting Mesos but at the same time we need to run it on top of OpenStack at some places. My main questions is about how and if autoscaling defined via HEAT templates works together. And has to be done. I assume that scaling up is not much a problem - when Mesos detects more resources it notifies frameworks which might scale based on their buildin strategies, though I assume it can't be defined in HEAT templates. Scaling down has to go through some cooperation between Mesos and HEAT. Do I have to update Mesos frameworks source code to somehow listen to OpenStack events or something like this?
Is there any ongoing effort from Mesosphere and OpenStack to integrate more closely in this regard? Many thanks for any points regarding other possible problems and any clarification, Petr
