A journey to SDN
2020-11-10, 09:30–10:00, Main Stage

How we use a pipeline to configure a SDN underlay with Mellanox and Cumulus Linux (now Nvidia) using GIT, Ansible, Eve-NG and GoCD.


What are the differences between underlay and overlay networks in SDN?
In my talk, I will present our move from classic network administration to Net(Dev)Ops using repositories,
stages and pipelines.
I will show how network administration changed from the early 90s until today. ("Evolution of Networker's toolset")
Focus is on the underlay network with our selection of hardware ("The vendor game") and tools.
You will get an overview of how we set up our environment using infrastructure as code (IaC).
