This session will explore why NFTables offer clear advantages over IPTables and IPVS, especially in large-scale production environments from both maintainers and end users perspective. We’ll share a user story who faced persistent issues with IPTables, saw some success with IPVS, and finally solved their scalability problems by migrating to NFTables. From a maintainers perspective we will showcase how and why NFTable outperforms the other proxy modes. We’ll provide performance insights and discuss kernel compatibility.
We will also discuss NFTables compatibility with various CNI providers and plugins, and how NFTables support is already integrated in many environments, providing a smoother transition. Attending this session you will get an indepth understanding of behavioral changes when migrating from IPTables and IPVS to NFTables, including key metrics to track.
