Open Stack

Hi Matthieu,
        
        You mentioned 15000 connections with 1000 compute nodes.
        Was that mostly Nova? Was ceilometer involved?
        I would be curious to know how much AMQP traffic is Control related (e.g. spinning up VMs) vs how much is telemetry related in a typical openstack deployment.
        Do we know that?
        
        I have also left some comments in the doc.

        Hi Ken,
        
        Thanks for starting this !
        I've made a first pass on the epad and left some notes and questions there.
        
        Best,
        
        Matthieu
