[keycloak-dev] domain mode changes

[Marek Posolda]

Do you think that people will use cluster with 2 nodes on localhost + 
embedded H2 + static loadbalancer in production? I guess not. So having 
our domain.xml "pre-set" to have easy example cluster setup won't help 
much IMO. Customers will be able to setup "easy" cluster in 5 minutes, 
but they will be unaware of all the steps they need to set the real 
"production" cluster.

Also there is inconsistency with Wildfly, which may lead to some other 
confusions (as you pointed in other thread for add-user script).

I think that what would be helpful is, to guide people through all the 
manual steps more deeply, so after "absolve" the tutorial, they will be 
able to set the domain with real production cluster in their environment 
with 2 remote nodes on different machines communicate between each 
other. And they will know the possibilities for setup real loadbalancer 
too (HTTPD+modcluster or Undertow+modcluster etc). But I am not sure how 
deep to go there, as loadbalancer is not directly our stuff...

Also maybe it would be helpful to have some guides for setup AWS or 
JGroups without Multicast, but with TCP and TCPPING. I know it's not our 
stuff, but you know... There were gazillion questions regarding this in 
last months ;-)
