vRealize Automation IaaS Web server provides a user interface within the vRealize Automation portal Web site for the administration and consumption of IaaS components.

The IaaS Website provides the infrastructure administration and service authoring capabilities to the vRealize Automation console. The Website component communicates with the Model Manager, which provides it with updates from the Distributed Execution Manager (DEM), proxy agents and database.

The Model Manager communicates with the database, the DEMs, and the portal website. The ModelManager is divided into two separately installable components — the Model Manager Web service and the Model Manager data component.

Note

The vRealize Automation IaaS Web server is a separate component from the vRealize Automation appliance.
