Table 52. Virtual Appliances and Appliance Database
Component Description
Single Sign-On Server Identity Appliance, a preconfigured virtual appliance that
provides Single Sign-On capabilities.
Alternatively, you can use some versions of the SSO provided
with vSphere. For information on supported versions, see
vRealize Automation Support Matrix.
vRealize Appliance A preconfigured virtual appliance that deploys the
vRealize Automation server. The server includes the
vRealize Automation console, which provides a single portal for
self-service provisioning and management of cloud services, as
well as authoring and administration.
Appliance Database Stores information required by the virtual appliances. The
database is embedded on one or two vRealize Appliances.
You can select the individual IaaS components you want to install and specify the installation location.
Table 53. IaaS Components
Component Description
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.
Manager Service The Manager Service coordinates communication between
agents, the database, Active Directory (or OpenLDAP), and
SMTP. The Manager Service communicates with the console
Web site through the Model Manager. This service requires
administrative privileges to run.
Model Manager The Model Manager communicates with the database, the
DEMs, and the portal website. The Model Manager is divided
into two separately installable components — the Model
Manager Web service and the Model Manager data component.
Distributed Execution Managers (Orchestrator and Worker) A Distributed Execution Manager (DEM) executes the business
logic of custom models, interacting with the IaaS database and
external databases. DEMs also manage cloud and physical
machines.
Agents Virtualization, integration, and WMI agents that communicate
with infrastructure resources.
Disabling Load Balancer Health Checks
Health checks ensure that a load balancer sends traffic only to nodes that are working. The load balancer
sends a health check at a specified frequency to every node. Nodes that exceed the failure threshold
become ineligible for new traffic.
