Julien Pivotto gave a presentation on DevOps at Agile Tour Louvain-la-Neuve in 2013. He defined DevOps as a cultural and professional movement that focuses on breaking down silos between development and operations teams. The key aspects of DevOps are culture, automation, measurement, and sharing. DevOps aims to build a unified team with shared goals and responsibilities through communication, trust, and giving everyone access and accountability.
