It looks to me this schedule as a service is not a service, and it more like an function with some changeable parameters. It needs many nova and cinder functions done first.

we know that there is a scheduler-as-a-service[1] working in progress now, aiming at smart resource placement and also providing the instance group API work for nova.


But what I wonder is does it include the feature of DRS(Distributed Resource Scheduler, something like that), as it is in vCenter[2], or is there any project related to this? or some related bp?


Any hints are appreciated. I apologize if this question was already covered and I missed it.




For the "smart" portion, maybe you should take a look at 
https://blueprints.launchpad.net/nova/+spec/solver-scheduler



And for the DRS feature, I think it's more likely to be fit in nova conductor's role. After all the migration task have been moved to conductor, then some feature like DRS could be discussed as the next step.
