Kris Buytaert has been involved in DevOps for 10 years, organizing 250 DevOps events across the world.

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.
