The system administrator can deploy multiple instances of the vRealize Automation appliance to ensure redundancy in a high-availability environment.
For each vRealize Automation appliance, you must enable time synchronization and add the appliance to a cluster. Configuration information based on settings for the initial (primary) vRealize Automation appliance is added automatically when you add the appliance to the cluster.
If you install a distributed installation with load balancers for high availability and failover, notify the team responsible for configuring your vRealize Automation environment. Your tenant administrators must configure Directories Management for high availability when they configure the link to your Active Directory.
