Devops means many things to many people. Even without a clear definition people instantly understand the problem space, while the solution space is much more complex and layered. In this talk on devops, different fields and practices will be presented, including how Devops is related to Agile and Lean, and the central roles that infrastructure as code, metrics and monitoring have. Many devops talks relate to the CAMS acronym : Culture, Automation, Measuring and Sharing. The S for Sharing is usually taken for granted and does not get much explanation, but in this talk it will be right in the centre. Without Sharing there is no Devops and successful adoption is impossible.
