DevOps Introduction @Cegeka
Patrick Debois gave an introduction to DevOps. He discussed how Agile development improved collaboration between developers and testers but neglected operations teams. Traditional continuous integration models separated development and operations. DevOps aims to bring development and operations teams together through practices like infrastructure as code, configuration management, continuous integration/delivery, and collaboration across roles. Culture and mindset shifts are also important for DevOps, prioritizing collaboration, craftsmanship, and trust between teams.
