In technology, the only thing you can be certain of is change. It's now 18 months since our first pull request to get Chef Provisioning working with Azure and we've seen a lot of change since that day. In this talk we'll reflect on how we've watched the Microsoft, Chef and DevOps communities grow, and how the values of open-source and sharing have made this possible. We'll share stories of our successes, frustrations and lessons learnt - including why you should never write a technical book, how much coffee is required to work for 24 hours straight, and featuring some live demos of the tools we've helped to build.
