OpenShift is the container service the Mass Open Cloud has deployed. If you haven't thought about containers it is useful to read a little bit about them in:

https://en.wikipedia.org/wiki/Operating-system-level_virtualization

Specifically, OpenShift uses docker containers (https://en.wikipedia.org/wiki/Docker_(software)). Docker containers have minimal storage requirements and are immutable. Being immutable implies that any information which contains state needs to be in persistent storage - this is sometime described with the terms ephemeral (no attached storage) and persistent (attached storage).

OpenShift uses kubernetes to orchestrate the deployment and management of the docker containers (https://en.wikipedia.org/wiki/Kubernetes). Additionally, OpenShift augments kubernetes with many features useful for enterprise, however this tutorial will concentrate on OpenShift's development/deployment process.
