OpenShift is a Platform as a Service. It's straightforward to deploy it on top of the Infrastructure as a Service platform OpenStack using Heat templates, in a way which allows it to grow as more resources are required. This presentation gives an overview of what OpenShift gives to developers, and how to deploy it on top of OpenStack.

3. Consolidated B-24 Liberator
Incredibly sophisticated. ~500k parts, assembled
by unskilled labor.
No manufacturing process. Parts were cast in
rubber molds, so every part was slightly different.
Assembled in the heat of San Diego, which
warped the metal and required whole assemblies
to be adjusted.

Ford Motor Co. brought a manufacturing process
…
unit production went from 250 planes a year to
650 planes a month.
THIS IS OUR CHALLENGE TODAY
