The vRealize Automation Appliance
The vRealize Automation appliance is a precongured Linux virtual appliance. The vRealize Automation
appliance is delivered as an open virtualization le that you deploy on existing virtualized infrastructure
such as vSphere.
The vRealize Automation appliance performs several functions central to vRealize Automation.
n
The appliance contains the server that hosts the vRealize Automation product portal, where users log in
to access self-service provisioning and management of cloud services.
n
The appliance manages single sign-on (SSO) for user authorization and authentication.
n
The appliance server hosts a management interface for vRealize Automation appliance seings.
n
The appliance includes a precongured PostgreSQL database used for internal vRealize Automation
appliance operations.
In large deployments with redundant appliances, the secondary appliance databases serve as replicas to
provide high availability.
n
The appliance includes a precongured instance of vRealize Orchestrator. vRealize Automation uses
vRealize Orchestrator workows and actions to extend its capabilities.
The embedded instance of vRealize Orchestrator is now recommended. In older deployments or special
cases, however, users might connect vRealize Automation to an external vRealize Orchestrator instead.
n
The appliance contains the downloadable Management Agent installer. All Windows servers that make
up your vRealize Automation IaaS must install the Management Agent.
The Management Agent registers IaaS Windows servers with the vRealize Automation appliance,
automates the installation and management of IaaS components, and collects support and telemetry
information.
Infrastructure as a Service
vRealize Automation IaaS consists of one or more Windows servers that work together to model and
provision systems in private, public, or hybrid cloud infrastructures.
You install vRealize Automation IaaS components on one or more virtual or physical Windows servers.
After installation, IaaS operations appear under the Infrastructure tab in the product interface.
IaaS consists of the following components, which can be installed together or separately, depending on
deployment size.
Web Server
The IaaS Web server provides infrastructure administration and service authoring to the
vRealize Automation product interface. The Web server component communicates with the Manager
Service, which provides updates from the Distributed Execution Manager (DEM), SQL Server database, and
agents.
Model Manager
vRealize Automation uses models to facilitate integration with external systems and databases. The models
implement business logic used by the DEM.
The Model Manager provides services and utilities for persisting, versioning, securing, and distributing
model elements. Model Manager is hosted on one of the IaaS Web servers and communicates with DEMs,
the SQL Server database, and the product interface Web site.
