Please note: This schedule is for OpenStack Active Technical Contributors participating in the Icehouse Design Summit sessions in Hong Kong. These are working sessions to determine the roadmap of the Icehouse release and make decisions across the project. To see the full OpenStack Summit schedule, including presentations, panels and workshops, go to http://openstacksummitnovember2013.sched.org.
An instance group provides a mechanism to describe a topology of instances and the relationships between them, including the policies that apply to them. This is useful to create/schedule a group of instances, where we would like to apply certain policies like “anti-affinity”, “network-proximity”, “group-affinity”, etc., to a specific set of groups, and create them as a whole.
This is highly applicable for the Smart Resource Placement effort, and the APIs are the starting point for making combined smart decisions for scheduling the entire topology.
