If you`ve hit the wall in between multiple container infrastructure orchestration platforms I think the potential this provides is pretty big, and will have a lot to say for Enterprise adoption.
Separating out the shared commodity container stack points towards plug-and-play cross-vendor container stacks based on standardized APIs. Puppet, Chef, Ansible, Azure, AWS, VmWare, Kubernetes, etc etc: todays market is a divergent mess. Being able to mix-and-match configuration tools, clustering tools, and management interfaces will get us to best-of-breed solutions. It should enable plug-and-play components that today, amidst a dizzying array of incompatibility, generally force you onto wholesale stacks.
Props to Docker for investing in the shared eco-system and risking the brand confusion to push the industry towards the next step.
This doesn`t impact users of Docker or containerized app devs, people won`t be setting up a Moby stackexchange site any time soon. This is big news for the devs of container platforms though :)
