The vRealize Orchestrator cluster is deployed to the same cluster as the vRealize Automation instances.

vSphere Cluster Design, defines the following clusters for the two-cluster implementation.

Management cluster

Shared Compute and Edge cluster

Compute payload cluster

The vRealize Orchestrator instance is logically a part of the management cluster.

Design Justification

Design Implication

SDDC-CMP-VRO-07

Deploy all vRealize Orchestrator instances required by the SDDC solution within the management cluster.

In this design, only the vRealize Automation component consumes vRealize Orchestrator.

None

SDDC-CMP-VRO-08

Configure load balancer for vRealize Orchestrator to utilize round-robin balancing algorithm without persistence.

Round-robin allows individual workflow requests to be balanced across vRealize Orchestrator nodes. Requests do not require persistence to a specific vRealize Orchestrator node.
