I have seen the document 'wildflyClusteringGuide_701.pdf' to setup the appliance in a cluster configuration. Document says we need additional soft appliances to be added as slave nodes in the cluster.
In my case, Customer has three h/w appliances for the production. To achieve high availability, what would be the best option with three appliances in place?
Note: Customer doesn't want to go ahead with Oracle DataGuard.
