After you deploy the appliances for vRealize Automation, you can set up a load balancer to distribute traffic among multiple instances of the vRealize Automation appliance.
The following list provides an overview of the general steps required to configure a load balancer for vRealize Automation traffic:
Install your load balancer.
Enable session affinity, also known as sticky sessions.
Ensure that the timeout on the load balancer is at least 100 seconds.
If your network or load balancer requires it, import a certificate to your load balancer. For information about trust relationships and certificates, see Certificate Trust Requirements in a Distributed Deployment. For information about extracting certificates, see Extracting Certificates and Private Keys
Configure the load balancer for vRealize Automation appliance traffic.
Configure the appliances for vRealize Automation. See Configuring Appliances for vRealize Automation.
When you set up virtual appliances under the load balancer, do so only for virtual appliances that have been configured for use with vRealize Automation. If unconfigured appliances are set up, you see fault responses.
