Clustering allows a single TERMINALFOUR instance to be clustered over multiple application servers. All updates are automatically propagated to other servers within the cluster to ensure a consistent experience between all clustered servers.

  • License keys can be tied to multiple servers.
  • All configuration information is shared.
  • All events within the system are serialized and propagated to all known servers in the cluster.
  • Scheduled tasks will always take place on a single server instance within the cluster.

 To configure Clustering, go to System administration > System settings > Clustering.
