I have no love for Riot-the-games-company, but there are pretty good reasons why Riot-the-software-company is so well-respected. Bear in mind that stuff like that blog post are just the upper crust of that iceberg. They basically took the notion of Chef best practices away from Opscode (now Chef, Inc.) and completely redefined them with environment cookbooks and Berkshelf. Things in devops have moved on somewhat, as they always do--but they were, and I assume still very much are, serious about building good processes and the tools necessary to make them better.
