K8s at Deutsche Bahn

This lecture was given by Gualter Barbas Baptista from DB Systel at the Containerdays from 05 to 07 September 2022. (https://www.containerdays.io/)

In 2016, Deutsche Bahn decided to get rid of their own data centers and to migrate the majority of applications to the cloud. The cloudification of Deutsche Bahn was supported by a comprehensive transformation of its digital partner DB Systel from traditional working and organisational structures to self-organisation and company-wide networks, including a DevOps culture. Within this context, the first Kubernetes platform services emerge. From an OpenShift-based Kubernetes-Namespace-as-a-Service into a GitOps based K8s fleet management, we describe how the cloud, the organisational transformation and the CNCF landscape are accelerating the digitalisation of Deutsche Bahn.
