Technical Thoughts on OpenShift and Docker

Key quote (for me)

> Portability and reducing lock-in have been core OpenShift values since we first announced. The truth of the matter is many of our users don't want to be locked in to OpenShift or any PaaS. We don't want them to be locked in either.

Not being tied to infrastructure is a pretty amazing feeling. Being able to switch from my VPS to OpenShift, some other Docker-enabled PaaS, bare metal, EC2, or my internal OpenStack cluster seamlessly offers a tremendous amount of choice.

I think the combination of Docker style LXC containers and kernel level MAC (i.e. SELinux) is a great approach and helps build upon the "high security" goals of OpenShift.

I was also happy to hear about the resources you're providing to help Docker run on more distros with a better approach to filesystem layering (dm thin). Red Hat is again demonstrating its commitment to and alignment with the larger open source community -- so thank you for that.

The team here at http://deis.io/ welcomes these efforts and looks forward to the development of a healthy Docker PaaS ecosystem.
