Configuring Your Load Balancer
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:
1 Install your load balancer.
2 Enable session affinity, also known as sticky sessions.
3 Ensure that the timeout on the load balancer is at least 100 seconds.
4 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
5 Configure the load balancer for vRealize Automation appliance traffic.
6 Configure the appliances for vRealize Automation. See Configuring Appliances for vRealize
Automation.
Note 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.
For more about load balancers, see the vRealize Automation Load Balancing Configuration Guide
technical white paper.
For information about scalability and high availability, see the vRealize Automation Reference
Architecture guide.
