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.
