Devops is not a new concept, but rather a growing movement that aims to break down barriers between development and operations teams. It promotes automating processes, measuring outcomes, and sharing knowledge across teams. The goals are to speed up delivery of features, improve reliability and safety, and make customers, developers and operations staff happier. Central to devops is adopting a culture of collaboration between teams through practices like continuous integration, infrastructure automation, and enabling fast and reliable software deployments.
