I have the following setup: a server running Ubuntu with WildFly installed, and two Debian servers functioning as slave nodes, all connected in a domain. I have deployed the application in two groups. My goal is to ensure that if one of the servers fails, the other continues to operate without interruptions, maintaining service availability for clusterjsp.war.
I have been researching high availability and found relevant information, but I am struggling to fully understand how to implement it in my environment. Could you help me configure high availability in WildFly so that the servers remain active even in the event of failures?
