Recomanded network setup for Rancher

Hi,
what is the best way for network setup to manage k8s clusters in hybrid cloud environment?
How to configure cards?
I found this article, but I do not use Ros.

It looks like this (in general it can be azure and any other cloud added on diagram)


I am running Rancher2 on Docker.

Suggestions?

Thank you.

Thank you in advance.
