vRealize Automation High
Availability Configuration
Considerations 7
If you require maximum system robustness, configure your vRealize Automation system for high
availability in accordance with VMware guidelines.
vRealize Automation Appliance
The vRealize Automation appliance supports active-active high availability. To enable high availability for
these appliances, place them under a load balancer. For more information, see Installing vRealize
Automation 7.0. Beginning with the 7.0 release, the appliance database, and vRealize Orchestrator are
automatically clustered and available for use.
vRealize Automation Directories Management
Each vRealize Automation appliance includes a connector that supports user authentication, although
only one connector is typically configured to perform directory synchronization. It does not matter which
connector you choose to serve as the sync connector. To support Directories Management high
availability, you must configure a second connector that corresponds to your second vRealize Automation
appliance, which connects to your Identity Provider and points to the same Active Directory. With this
configuration, if one appliance fails, the other takes over management of user authentication.
In a high availability environment, all nodes must serve the same set of Active Directories, users,
authentication methods, etc. The most direct method to accomplish this is to promote the Identity Provider
to the cluster by setting the load balancer host as the Identity Provider host. With this configuration, all
authentication requests are directed to the load balancer, which forwards the request to either connector
as appropriate.
For more information about configuring Directories Management for high availability, see Configuring
vRealize Automation.
Infrastructure Web Server
The Infrastructure Web server components all support active-active high availability. To enable high
availability for these components, place them under a load balancer.
