I recently evaluated all 3 solutions. Here is how I see it after testing the waters:
- want something simple that works today? Docker Swarm
- want something amazingly flexible? Kubernetes
- already use Mesos or DC/OS? Marathon/Mesos
This article from Mesosphere is interesting and gives a good overview, but it downplays advantages of Swarm and Kubernetes and clearly highlights Mesos: Docker has 4 bullet points, Kubernetes has 3 and Mesos has 5.
In addition, Marathon is meant to work on Mesosphere DC/OS and not on other operating systems. For instance, the "Virtual IP" [1] feature only works on DC/OS from what I can tell. This confused me because this feature appears on the UI even if you run Ubuntu, it just doesn't work in that setup.
Docker Swarm seems to have a very comparable feature set, but doesn't care what OS you run.
There is an Me

sos plugin for Kubernetes [2] but it looks unmaintained, so this sentence seems a bit off: "Mesos could even run Kubernetes or other container orchestrators, though a public integration is not yet available." This also goes to show how important community support and commercial backing is and Kubernetes is the clear winner here.
At the end, you can read this: "want all of this portable across cloud providers and/or datacenters, then Mesos (or our own Mesos distribution, Mesosphere DC/OS)". With Docker Swarm, you can use multiple cloud providers. Docker Swarm does not care about what servers you use. It encrypts traffic between nodes and needs Docker. That's it. It is cloud agnostic. I'm not sure what the story is with Kubernetes here. Kubernetes is a huge beast: very flexible and powerful, but a high upfront setup cost when you want to manage everything yourself.
