A system administrator can deploy vRealize Automation in a distributed configuration, which provides failover protection and high-availability through redundancy.

The Distributed Deployment Checklist provides a high-level overview of the steps required to perform a distributed installation.

Table 1. Distributed Deployment Checklist

Task

Details

Check Box Plan and prepare the installation environment and verify that all installation prerequisites are met.

Preparing for Installation

Check BoxPlan for and obtain your SSL certificates.

Certificate Trust Requirements in a Distributed Deployment

Check Box Deploy the Identity Appliance, the lead vRealize Appliance server, and any additional appliances you require for redundancy and high availability.

Deploy Appliances for vRealize Automation

Check Box Configure your load balancer to handle vRealize Automation appliance traffic.

Configuring Your Load Balancer

Check Box Configure the Identity Appliance, lead vRealize Appliance server, and any additional appliances you deployed for redundancy and high availability.

Configuring Appliances for vRealize Automation

Check Box Configure your load balancer to handle the vRealize Automation IaaS component traffic and install vRealize Automation IaaS components.

Install the IaaS Components in a Distributed Configuration

Check Box If required, install agents to integrate with external systems.

Installing Agents

Check Box Configure the default tenant and provide the IaaS license.

Configuring Initial Access

High-Availability for the Identity Appliance

High-availability and failover protection for the Identity Appliance is handled outside of vRealize Appliance. Use a vSphere HA-enabled cluster to protect the virtual appliance. For more information, see the vSphere documentation center.

vRealize Orchestrator

Use external implementations of vRealize Orchestrator with high-availability deployments. If you use a vRealize Orchestrator server on a vRealize Appliance, configure it to be external. Embedded versions should never be used.
