If you believe OpenStack and OpenShift are pretty much the same thing. you better listen to this episode with Martin Etmajer ( https://twitter.com/metmajer ). He explains what OpenShift is, how it differentiates from Cloud Foundry and other PaaS platforms, and which major contribution it can have to successful DevOps transformations.

To put it in his words: OpenShift provides great user experience for developers to push their code changes automatically, packaged as containers, into different environments without having to worry about where and how these containers run or how they scale up & down. You should also check out his presentations from Red Hat Summit on Monitoring and Logging in OpenShift ( https://www.slideshare.net/martinetmajer ) as well as more material on http://www.dynatrace.com/openshift.
