10 years of #devopsdays, but what have we really learned ?

Kris Buytaert has been involved in DevOps for 10 years, organizing 250 DevOps events across the world. While tools have evolved from things like Puppet and Chef to Docker and Kubernetes, the most important lessons are about culture change and people. Many organizations have paid lip service to DevOps without truly changing culture and processes, and resistance to change remains a major barrier. The future of DevOps is about continual learning and helping others change.
