Ok, so if we proceed using Swarm as our first pursuit, and we want to add things to Swarm like scheduling hints, we should open a Magnum bug ticket to track each of the upstream patches, and I can help to bird dog those. We should not shy away from upstream
enhancements until we get firm feedback suggesting our contributions are out of scope.

1) Cherry pick scheduler code from Nova, which already has a working a filter scheduler design.<br>
2) Integrate swarmd to leverage its scheduler[2].</blockquote>

</div>
<div>I see #2 as not an alternative but possibly an "also". Swarm uses the Docker API, although they're only about 75% compatible at the moment. Ideally, the Docker backend would work with both single docker hosts and clusters of Docker machines powered by
Swarm. It would be nice, however, if scheduler hints could be passed from Magnum to Swarm.</div>

<div>Adrian & Eric,</div>
<div><br>
</div>
<div>I would prefer to keep things simple and just integrate directly with swarm and leave out any cherry-picking from Nova. It would be better to integrate scheduling hints into Swarm, but I’m sure the swarm upstream is busy with requests and this may be difficult
to achieve.</div>
