In 2009, the general understanding in the IT industry was that projects would run late, underperform, or simply fail, resulting in fear and resistance from business users. Despite the advancements following the Agile Manifesto, iterative development was failing to complete the “last mile” to continuous delivery.
Patrick Debois introduced the term “devops” to capture his vision for a future where developers and sysadmins would work together to deliver reliable software faster. Since then, the movement has evolved to DevSecOps—incorporating security into the culture, principles, and processes created to streamline software release cycles.
