Obviously I am biased (working on Docker), but I thought I would mention a few facts. - Today AWS announced they would support Docker Swarm and Compose natively on ECS. - Last month devops.com surveyed development and ops teams about their usage of containers. Their conclusion was: "While this is still a nascent market, some early leaders did emerge from the responses. Docker Swarm, the orchestration technology from Docker itself, was the clear winner, with nearly 50% of respondents indicating that they planned to investigate Swarm. Close behind were Kubernetes and Mesos." Personally I think the important part of that quote is "this is still a nascent market". We are the very, very beginning of these sorts of platforms, and nobody really knows what these platforms will evolve to be in a few years. So I really don't think it matters who has the most "market share" of the 0.00001% of IT organizations actually aware of these tools. The innovation is only just getting started.
