During Puppet Camp Paris, I got the privilege to present the Continuous Delivery Workflow of TubeMogul’s Operations Engineering Team. In few years, we went from few servers to over two thousands nodes fully managed by Puppet. In our presentation, we went over the challenges we faced as well as the implementation of our workflow to improve our day to day operation while still moving fast.

With our operations continuous delivery workflow using Git, Gerrit, and Jenkins, we have been able to manage over 10,000 Puppet deployment in 2014.
