Thanks for your insight!

Do you happen to have experience with a large number of realms in Keycloak? I was looking at it a while ago and found conflicting opinions on how suitable realms would be to model multi tenancy in a saas. Mainly for performance reasons I think.

Hmm no, sorry. We only ever had a small number of realms. I would be cautious and test it with the number of realms you intend to use it with. We used locust (https://locust.io/) successfully to do loadtesting on a few of keycloaks auth flows.
