How do you bring a DevOps practice to an existing application? While at NDC London, Carl and Richard talk to Damian Brady about his experiences working with teams trying to get better at building, deploying, instrumenting and maintaining existing applications. Often the processes put in place when an application is first developed stay the same - new techniques are applied to new apps. But it doesn't have to be like that! Damian talks about engaging everyone involved in the app, including management, development, QA, data folks, operations and more to work toward a better, more reliable application. And the results are worth it!
