• Deutsche Telekom faced challenges in implementing Kubernetes at scale and speed in a complex on-prem environment on bare metal.
• Legacy network and network legacy were some of their biggest enemies.
• They reimagined and implemented a network fabric for on-prem bare metal Kubernetes cloud that supports their internal Cluster-as-a-Service offering.
• Their cloud is hosting clusters where some of their most demanding applications like 5G core are running.
• They are building an internal GitHub Kubernetes cluster-as-a-service platform almost exclusively using open source components.
• They want to reliably build Kubernetes clusters with well-defined APIs for their customers and integrate network functions into the platform.
• They work upstream first and want to work with the community to build and contribute back.
• They use BGP and IP fabrics to manage network traffic flow.
