With that said, I often wonder how many people are using Mesos/Marathon before they have any need for it? Using it on for 4 hosts vs. 40 or 400?
Anything more than a single host requires additional co-ordination - picking Mesos is mostly no different than rolling alternate methods for doing so.
It's not choice with the least overhead, but it's a possibility, for those for whom it has the right conveniences...
