In IT since 2007, starting as java dev to then embrace the DevOps culture in order to help build better operated software.
Joined the Kubernetes journey in 2016 and never looked back since.
Pushing and managing Kubernetes everywhere : in the Cloud, datacenters, trains and soon train stations (hopefully !)
Loves food and will happily help anybody looking for a good restaurant in the Lyon vinicity (trust me it's worth it !)

Revolutionizing Railways: How Edge Technology Solves Decades-old IT Infrastructure Challenges
This presentations talks about redefining railway systems using the transformative power of a cloud-native approach. Despite their pivotal role in our future, trains often grapple with outdated IT structures, turning what should be day-to-day operations to year-long plannings. Implementing Cloud-native minded Edge technology in commercial trains since this year, we do not only addresse this multi-decade conundrum but also revolutionize observability, ensuring heightened insights into system performance.
This allow us to enhance safety, efficiency and ultimatly elevate passenger experience. Through GitOps, we achieve a paradigm shift by empowering seamless integration and deployment across multiple railway networks. These innovative approach bolster network resilience, fortifying railways against disruptions and obsolescence.
Edge technology may redefine railway infrastructure, bridging the gap between tradition and modernity, in order to forge an more innovative and resilient future.

Keeping Sovereignty on Track: Kubernetes Powering a National Railway Platform
As France’s national railway operator, SNCF has always treated data governance and operational control as mission-critical. That priority became even more urgent when we launched our large-scale cloud migration program in 2018.
Today, 70% of our 2,000 applications run across public clouds, modernized through containers, serverless architectures, and managed services. Kubernetes quickly became a central pillar of this transformation and now powers roughly 30% of our application portfolio. At scale—operating more than 200 Kubernetes clusters across Azure and AWS—we learned that Kubernetes is not just a container orchestrator; it is the control plane for modern application platforms.
But we also learned something deeper: Kubernetes performs best when it runs on infrastructure that is predictable, programmable, and fully under your control. Networking, storage, compute, and load balancing must be designed to serve Kubernetes—not constrain it.
To bring that level of control to our remaining on premise workloads, we built our private cloud strategy around Kubernetes and full automation. In 2023, we selected OpenStack to provide the infrastructure layer beneath it, enabling us to deliver a cloud-native platform with public-cloud parity while maintaining sovereignty and governance requirements. In addition Openstack allows us to serve simple architectural patterns based on Virtual Machines, simple solutions for simple needs.
The overall result is a high-performance, open-source platform where Kubernetes is the consistent abstraction layer across every environment—public and private—allowing us to continue modernizing applications at scale while retaining full control of our infrastructure's future.
