This document discusses the evolution of devops concepts and tools over the past 10 years since the devops movement began. It notes that early topics focused on culture, automation and monitoring tools. Over time, tooling became more advanced but also more complex. Culture remains important but large enterprises still struggle with devops adoption due to broken cultures. New technologies like containers have created new challenges. Ultimately, devops is about change and people, not just tools. While progress has been made, there is still work to be done to fully implement devops principles and fix issues around tool hype, broken cultures and burnout.
