In the previous chapters, we focused on improving the creation and management of infrastructure. The DevOps culture doesn't stop there, however. As you might recall from Chapter 1, The Cloud and the DevOps Revolution, DevOps culture also includes having a very efficient process to test and deploy code. At the 2009 Velocity conference, John Allspaw and Paul Hammond made a very inspirational speech about how Flickr was carrying out over 10 deployments a day (http://bit.ly/292ASlW). This presentation is often mentioned as a pivotal moment that contributed to the creation of the DevOps movement. In their presentation, John and Paul talk about the conflicts between development and operations teams but also outline a number of best practices that allow Flickr to deploy new code to production multiple times a day.
