This document discusses the history of devops from 2009 to the present. It began as a movement in 2009 in Ghent to improve software delivery using open source tools and has since grown globally with over 250 events held. While tools have evolved from things like Puppet and Jenkins to Docker and Kubernetes, the core challenges of culture change, continuous delivery, monitoring, and cloud infrastructure remain. The document cautions that tools alone will not solve problems and that the industry focuses too much on hype and certification over meaningful change. The key takeaway is that after over 10 years, many organizations still struggle with devops principles due to cultural barriers, and the work of bridging development and operations is ongoing.
