Modern networks demand dynamic, scalable automation, yet managing complex networks remains a challenge. At Swisscom, we tackled this by building a Kubernetes Resource Model (KRM)-powered automation framework that transforms high-level user intents into production-ready network configurations, in seconds, not weeks. By integrating MetalLB load balancing and NetBox IP address management, we created an efficient, repeatable, and scalable workflow. In this talk, we’ll showcase our automation in action, demonstrating how we launch the Network of a 5G Core in minutes. We’ll highlight key productivity gains, share best practices, and discuss lessons learned from scaling network automation. You will learn about automation frameworks and our own experience building Kubernetes Operators such as the open-source Netbox Operator. Join us to see how cloud-native automation is transforming networking, and why Kubernetes Operators are the key to faster, smarter, and more flexible network operations.
