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.

主题: Re: [openstack-dev] [Scheduler] about scheduler-as-a-service

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.

BTW, the second link you provided seems to be in Chinese. For those who
interested, please use this one instead.
