Dear Stackers, Ice-house 3 deadline is approaching quickly and we still need reviews & approval for Policy Based Scheduler ! So I kindly ask for your attention for this blueprint.
The purpose of this blueprint is to manage the scheduling process by the policy. With it admin can define scheduling rules per group of physical resources (an aggregate, an availability-zone, or the whole infrastructure); or per (classes of) users. For instance, admin can define a policy of Load Balancing (distribute workload evenly among the servers) in some aggregates, and Consolidation (concentrate workloads in minimal of servers to be able to hibernate others) in other aggregates. Admin can also change the policies in runtime and the changes will immediately take effect. Among the usecases would be the Pclouds : https://blueprints.launchpad.net/nova/+spec/whole-host-allocation where we need a scheduling configuration/decision per Pclouds. It can be done easily by defining a policy to each Pclouds. Future development of the policy system will even allow users to define their own rules in their Pclouds!
