Yes; apologies if that wasn't clear.
The original point was that there are frameworks available which do scaling within their own contexts, but I agree that I've not seen anything that does the scaling of Mesos slaves themselves yet (hence the h/t to Sharma for the slidedeck).

I will search for that and good to know Jenkins Mesos framework also does that work.

One thing you might find interesting, Kenneth, is the Jenkins Mesos framework which does automatic slave provisioning and horizontal scaling.

Theoretically, scaling up can be relatively easy by watching the utilization and adding nodes. However, in order to scale down, the framework must support two things - some kind of bin packing so it uses as few slaves as possible, and a call out to which slaves can be shutdown. I discussed how we achieve this at last year's MesosCon and also at AWS re:Invent, slides from which are at http://www.slideshare.net/spodila/aws-reinvent-2014-talk-scheduling-using-apache-mesos-in-the-cloud in case that helps you with ideas.

It run as expected and it is great to scaling app to as many instance as it needs. However, I have a question came up and I tried to find out the related information to see how Mesos could automatically scaling the slaves as many as need on the hardware/machines, but seems not many details on how it works, how the process. Do we need to have another layer to watch, provision nodes on demand on Paas so the new nodes could automatically join Mesos cluster, or Mesos could also handle that kind of task. Appreciated if any of related information/documents. Thanks! Kenneth
