+The talk started with a base introduction of ClusterAPI and the operations at gigantswarm.

+TODO: Diagram
+
+Product naming for the next noted:
+- `vintage`: Legacy system
+- `CAPI`: The new shit

+TODO: Sequence diagram
+

+- Implementing new providers (GCP, Openstack, etc) is way simpler nowadays
+- There is a timepline from custom tooling over product to commodity
+
+## Q&A
+
+- Were there any fears from the customers regarding the migration?
+    - There are some but long term relations to customers help
