You only have to change one thing to make DevOps work, Everything
The speaker discusses changes organizations can make to enable DevOps. They recommend: redefining terminology to fit the organization; structuring teams around products rather than functions; using modern architectures like microservices and containers; and implementing continuous delivery practices to deploy changes safely and frequently. The overarching message is that changing organizational culture and structure, not just processes or tools, is key to making DevOps work.

- 20. @kmugrage@kmugrage “GIVING DEVELOPERS OPERATIONALRESPONSIBILITIES HAS GREATLY ENHANCED THE QUALITY OF THE SERVICES, BOTH FROM A CUSTOMER AND A TECHNOLOGY POINT OF VIEW. THE TRADITIONAL MODEL IS THAT YOU TAKE YOUR SOFTWARE TO THE WALL THAT SEPARATES DEVELOPMENT AND OPERATIONS, AND THROW IT OVER AND THEN FORGET ABOUT IT. NOT AT AMAZON. YOU BUILD IT, YOU RUN IT. THIS BRINGS DEVELOPERS INTO CONTACT WITH THE DAY-TO-DAY OPERATION OF THEIR SOFTWARE. IT ALSO BRINGS THEM INTO DAY-TO-DAY CONTACT WITH THE CUSTOMER. THIS CUSTOMER FEEDBACK LOOP IS ESSENTIAL FOR IMPROVING THE QUALITY OF THE SERVICE.” –Werner Vogels, Amazon https://queue.acm.org/detail.cfm?id=1142065
