Jeff Geerling (geerlingguy) presented the 2018 Keynote at NEDCamp in Providence RI, on "Real World DevOps". There are plenty of buzzword-worthy tools and processes that make up the industry's definition of DevOps—but if you actually want to make your team happier, and your team's applications better, how do you do that with DevOps? This presentation answers that question and distills some of the heady DevOps principles in a way that's approachable for any team—whether 1 or a dozen!
