I am confused. At Multi-site deployments - Keycloak I read
Keycloak supports deployments that consist of multiple Keycloak instances that connect to each other using its Infinispan caches; load balancers can distribute the load evenly across those instances. Those setups are intended for a transparent network on a single site
At Concepts for multi-site deployments - Keycloak I see the exact same components for a multi-site scenario. Thus what is the difference?
Also at Concepts for multi-site deployments - Keycloak
Understand multi-site deployment with synchronous replication
Is there also a deployment with asynchronous replication or relying on some other technique?
