Zane also raised an important point about value. Any scheduler is serving one master most directly, the cloud provider. Any sane cloud provider has some interest in serving the interests of the cloud users, as well as having some concerns of its own. The way my group has resolved this is in the translation from the incoming requests to the underlying optimization problem that is solved for placement; in that translation we fold in the cloud provider's interests as well as the cloud user's. We currently have a fixed opinion of the cloud provider's interests; generalizing that is a possible direction for future progress.
It's good that you've considered this. I guess the gist of my question was: do you think that public cloud providers in particular would feel the need to bill for some aspect of this service if they provided it? (And, if so, how?)
The benefits to at least some private cloud providers (particularly the ones using OpenStack for enterprisey pets-not-cattle workloads) seem pretty obvious, but particularly if we're talking about incorporating holistic scheduling into an existing service then we need to make sure this is something that benefits the whole OpenStack community.
cheers, Zane. _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
