[keycloak-user] AWS ELB

[John Bartko]

I believe it is the case that either nodes must replicate the session cache, or the LB must use some sort of session affinity.

I believe this is pretty well documented somewhere.

Unless I recall incorrectly, Even with multiple node in standalone you still need clustering setup for many operations. Since clustering uses multicast by default you'll need to use jgroups backed by a database provider of some sort.

If you search around I believe this is all out on documentation you might need to search jboss docs instead of keycloak though.

Hi.

My company plans to use KC for central authentication and authorization
for multiple microservice backends and frontends.
Since all our services are running on AWS, we're wondering whether it is
a problem to use the AWS ELBs and not the wildfly clustering.

So my question is, is it a requirement to use the wildfly clustering
capabilities to be able to get a working, scalable KC?
What might not work or even break if we just load balance against
isolated KC instances which maybe share the same storage/db?

Thanks!
