Keynote: Keeping Sovereignty on Track: Kubernetes Powering a Nationa... Thomas Comtet & Yann Rotilio

This talk features Thomas Comtet and Yann Rotilio from SNCF, discussing how Kubernetes underpins France’s national railway platform amid a large-scale cloud migration. SNCF's transformation has led to 70% of their applications operating in public clouds, with Kubernetes managing approximately 30% of their application portfolio. The speakers delve into the critical lessons learned from scaling over 200 Kubernetes clusters across Azure and AWS, highlighting the importance of predictable and programmable infrastructure for optimal Kubernetes performance. They also describe the implementation of OpenStack to support their private cloud strategy, which allows them to achieve public-cloud parity while meeting governance requirements and optimizing their application modernization efforts.
