DevOps and NetOps are revolutionizing how we manage networks in SDN environments. They bring software development practices to networking, making things faster and more reliable. It's all about automating tasks, working together better, and keeping a close eye on how everything's running.
These approaches use cool tools like CI/CD pipelines and Infrastructure as Code to speed up network changes. They also focus on testing, monitoring, and using data to make smart decisions. It's a whole new way of thinking about networks that's changing the game for network pros.
