[keycloak-user] Load Balancer and Domain Clustered Mode

Hi, The docu said we should use our own load balancer. Is nginx a good idea there and how is the general rough setup then? Nginx in front, Domain controller is admin only and just controls the config, 2 slaves with an open Port (8080, 8081) which the load balancer uses? Or does the Domain Controller has some another role in this setup? Not asking for specifics, just the general workflow. Greetings Marc
