SKFS should always be installed in a clustered configuration for High Availability(HA) in a production environment. All the servers function in a master-master configuration where any server can receive transactions and will asynchronously replicate data records between all other nodes in the cluster without human intervention. They also provide business continuity (BC) in the event of a disaster affecting a location where the services of one (set of) FIDO2 server(s) may be affected.
