Chef is an amazing tool but to really unlock its potential you need to look at how it integrates with the rest of your technology. This presentation is the story of how the NFL used Chef to transform its siloed infrastructure and practices into something more agile, automated, and reliable.

This presentation will talk about the last 2 years of Chef at the NFL including how we integrated it into our virtualization infrastructure, load balancers, storage, and application performance monitoring. We'll talk about some things that Chef taught us about infrastructure-as-code that we were able to apply to other areas, and things we learned to make our cookbooks easier to manage across groups.
