Configuring Your Load Balancer
After you deploy the appliances for vRealize Automation, you can set up a load balancer to distribute trac
among multiple instances of the vRealize Automation appliance.
The following list provides an overview of the general steps required to congure a load balancer for
vRealize Automation trac:
1 Install your load balancer.
2 Enable session anity, 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 certicate to your load balancer. For information
about trust relationships and certicates, see “Certicate Trust Requirements in a Distributed
Deployment,” on page 63. For information about extracting certicates, see “Extracting Certicates and
Private Keys,” on page 30
5 Congure the load balancer for vRealize Automation appliance trac.
6 Congure the appliances for vRealize Automation. See “Conguring Appliances for vRealize
Automation,” on page 68.
N When you set up virtual appliances under the load balancer, do so only for virtual appliances that
have been congured for use with vRealize Automation. If uncongured appliances are set up, you see fault
responses.
For information about scalability and high availability, see the vRealize Automation Reference Architecture
guide.
Configuring Appliances for vRealize Automation
After deploying your appliances and conguring load balancing, you congure the appliances for
vRealize Automation.
Configure the Primary vRealize Automation Appliance
The vRealize Automation appliance is a precongured virtual appliance that deploys the
vRealize Automation server and Web console (the user portal). It is delivered as an open virtualization
format (OVF) template. The system administrator downloads the appliance and deploys it into the vCenter
Server or ESX/ESXi inventory.
If your network or load balancer requires it, the certicate you congure for the primary instance of the
appliance is copied to the load balancer and additional appliance instances in subsequent procedures.
Prerequisites
n
“Deploy the vRealize Automation Appliance,” on page 66.
n
Get a domain certicate for the vRealize Automation appliance.
Procedure
1 Enable Time Synchronization on the vRealize Automation appliance on page 69
Clocks on the vRealize Automation appliance server and Windows servers must be synchronized to
ensure a successful installation.
2 Congure the vRealize Automation Appliance on page 69
To prepare the vRealize Automation appliance for use, you congure host seings, generate an SSL
certicate, and provide SSO connection information.
