This design uses NSX logical switches to abstract the vRealize Automation application and its supporting services. This abstraction allows the application to be hosted in any given region regardless of the underlying physical infrastructure such as network subnets, compute hardware, or storage types. This design places the core vRealize Automation application and its supporting services in the hub. The same instance of the application manages workloads in all Regions and ROBO locations.

Design Justification

Design Implication

ROBO-CMP-001

Utilize a single vRealize Automation installation to manage Region A, Region B, and ROBO deployments from a single instance.

vRealize Automation can manage one or more regions as well as ROBO locations. This provides a single consumption portal regardless of region or ROBO location.

The abstraction of the vRealize Automation application over virtual networking allows it to be independent from any physical site locations or hardware.

You must size vRealize Automation to accommodate multi-region and ROBO deployments.

vRealize Automation supports only ten connected vCenter Servers.

Decision ID

Design Decision

Design Justification

Design Implication

ROBO-CMP-002

Apply vSphere Distributed Resource Scheduler (DRS) anti-affinity rules to the vRealize Automation components

Using DRS prevents vRealize Automation nodes from residing on the same ESXi host and thereby risking the cluster's high availability capability

Additional configuration is required to set up anti-affinity rules.

Decision ID

Design Decision

Design Justification

Design Implication

ROBO-CMP-003

vRealize Automation IaaS Machines are joined to Active Directory.

This is a hard requirement for vRealize Automation

Active Directory access must be provided using dedicated service accounts
