vRealize Orchestrator
The vRealize Automation appliance includes an embedded version of vRealize Orchestrator that is now
recommended for use with new installations. In older deployments or special cases, however, users might
connect vRealize Automation to a separate, external vRealize Orchestrator. See
https://www.vmware.com/products/vrealize-orchestrator.html.
For information about connecting vRealize Automation and vRealize Orchestrator, see Using the vRealize
Orchestrator Plug-In for vRealize Automation.
Directories Management
If you install a distributed installation with load balancers for high availability and failover, notify the team
responsible for configuring your vRealize Automation environment. Your tenant administrators must
configure Directories Management for high availability when they configure the link to your Active
Directory.
For more information about configuring Directories Management for high availability, see the Configuring
vRealize Automation guide.
Disabling Load Balancer Health Checks
Health checks ensure that a load balancer sends traffic only to nodes that are working. The load balancer
sends a health check at a specified frequency to every node. Nodes that exceed the failure threshold
become ineligible for new traffic.
For workload distribution and failover, you can place multiple vRealize Automation appliances behind a
load balancer. In addition, you can place multiple IaaS Web servers and multiple IaaS Manager Service
servers behind their respective load balancers.
When using load balancers, do not allow the load balancers to send health checks at any time during
installation. Health checks might interfere with installation or cause the installation to behave
unpredictably.
n
When deploying vRealize Automation appliance or IaaS components behind existing load balancers,
disable health checks on all load balancers in the proposed configuration before installing any
components.
n
After installing and configuring all of vRealize Automation, including all vRealize Automation
appliance and IaaS components, you may re-enable health checks.
Certificate Trust Requirements in a Distributed Deployment
vRealize Automation uses certificates to maintain trust relationships and provide secure communication
among components in distributed deployments.
