Well, I would say all of those companies are convinced of the open source container engine itself, but much less around Swarm, Compose, and the other components. In particular, Mesos seems super strong in the orchestration/scheduling layer, and its not clear that Docker will be able to dislodge them.

I honestly think it solves a different problem. Apple runs Siri on the biggest mesos cluster in the world (pretty much verbatim quote from MesosCon 2015. I was there). Twitter runs clusters over 10k physical nodes. Swarm and compose are cute, but they simply aren't made for that kind of massive scale. The inverse of course, is that they are incredibly easy to setup, and they work for a very large number of workloads reasonably well. I manage mesos clusters as part of $day_job. There is a certain level of setup required and if you don't need the scale, you simply don't need mesos for it. I really see them as complementary in the longer term. Perhaps a swarm mesos framework could be written. It is highly unlikely that Docker will ever do the resource scheduling better than Mesos.

  Great points. There is a swarm/mesos integration whereby the Swarm API is offered to the developer but it uses the Mesos framework to do the scheduling. It works, and there's more to come in terms of demos around the corner.

    And that is the sweet spot where you get the ease of swarm with the scalability of mesos. Win/win

Both Microsoft and Amazon have deeply integrated Swarm & Compose, with more coming. Both Microsoft and Amazon offer the Docker Subscription service on their respective Marketplaces and have active campaigns to promote them. There are Docker Machine drivers that operate with every major cloud provider, allowing you to spin up new Docker nodes in seconds. And as mentioned elsewhere in the thread, swarm integrates with Mesos and you can imagine any pure resource scheduler/framework can be integrated. Our goal is to provide the Docker experience to developers while being able to target disparate infrastructures, some of which are built purely with Docker and others built with an aggregation of tools.
