Prerequisite Knowledge

Engineers who follow the link on the final slide will be given far more technical details and examples...for those folks, an understanding of BASH, python, puppet, terraform, consul, AWS, github would be useful.


Everyone loves talking about different stacks used in migrating applications to DevOps methodologies, but the most important and valuable change is not a technology stack; instead, it is the human stack.

In this keynote address, we will cover the intersection of technology and humans, and walk the audience through a real life example of the move of Firefox crash reporter. The three engineers tasked with this had to build the plane while it was in the air, all without landing or crashing.

As with many projects, hard deadlines and requirements made the team work through a lot of tough decisions and compromises while simultaneously training devs, product managers, managers, and other engineers in the new world of DevOps and Continuous Delivery.
