The vRealize Automation IaaS Proxy Agent communicates with endpoints of a certain type of infrastructure. In this design, you use the vSphere Proxy Agent is to communicate with vCenter Server. Consider the number of instances according to the design objectives and the sizing for them.

The IaaS Proxy Agent server provides the following functions:

  • vRealize Automation IaaS proxy agent can interact with different types of infrastructure components.

  • To provision and manage the virtual machines, vRealize Automation sends requests for resource virtualization to vSphere. It uses vSphere Proxy agents to send commands to and collect data from vSphere.

Design Implication

ROBO-CMP-003

Deploy two vRealize Automation IaaS Proxy Agent virtual machines in each ROBO site.

Provides redundancy for vSphere connectivity.

You must provide more resources because you deploy multiple virtual machines for this function.
