Keynote: Keeping Sovereignty on Track: Kubernetes Powering a Nationa... T. Comtet & Y. Rotilio (ASL)

This talk focuses on the role of Kubernetes in powering France’s national railway platform, presented by Thomas Comtet and Yann Rotilio from SNCF. The speakers discuss SNCF's journey through a large-scale cloud migration that began in 2018, leading to the modernization of 70% of their 2,000 applications using containers, serverless architectures, and managed services. They explain how Kubernetes became a crucial component of this transformation, operating over 200 clusters across Azure and AWS, while emphasizing the importance of a controllable infrastructure for optimal performance. By implementing a private cloud strategy based on Kubernetes and OpenStack, SNCF has achieved a highly performant, open-source platform that ensures sovereignty and governance, facilitating modern application development across both public and private environments.
