Very good article. I understand, that your shop is Hashicorp shop. So Nomad is definitely very good choice.
IMHO, good alternative if you are in Docker as tool, not containers in general (let's leave open containers outside). Docker Swarm is good contender for schedulers, due one important thing: Docker will be needed to get back VC money. And Enterprise is only answer to this. This can be seen that for example Docker has got already working secrets in free version and in ent subs there is much more granularity etc.
Plus networking is not such wild west as it's in Kubernetes.
