Number Description Requirements and Options
1 vRealize Appliance Load
Balancer
Only necessary if you are deploying more than one vRealize Appliance.
Important Disable all nodes under the load balancer except for the node you are
configuring. For example, if you have three nodes, disable nodes 1 and 2 when you
configure node 3.
2 Single Sign-On Server
Appliance
One instance of a single sign-on server is required. You can use the vRealize
Appliance, which is a product component, or some versions of vSphere SSO, which
might be preferable for high-availability deployments. Consult the vCloud Automation
Center Support Matrix for information about supported versions.
3 vRealize Appliance 1 One instance required. Multiple instances can be used to support high availability and
failover recovery. Multiple instances must be deployed with vSphere High Availability.
4 vRealize Appliance 2, 3,
and so on
Deploy multiple instances under the vRealize Appliance Load Balancer.
5 Appliance Database Appliance Database or cluster. If a two vRealize Appliances have been deployed with
Appliance Databases, then they can be clustered. If only one vRealize appliance
exists, then there is no highly available method for the database.
6 IaaS Web Load Balancer Only necessary if you are installing more than one Website Component. Install Website
Component 1 and Model Manager Data on one machine under this load balancer.
7 SQL Database Cluster Install one instance during IaaS installation. Database administrator handles
redundancy outside of IaaS context. See Choosing an IaaS Database Scenario.
8 Website Component 1 and
Model Manager Data
Required. Install together on one machine under the IaaS Web load balancer. Only one
instance of Model Manager Data is allowed. See Install the Primary IaaS Website
Component with Model Manager Data
9 Website Component 2, 3,
and so on
Optional. Install multiple instances under the IaaS Web load balancer for high
availability and failover recovery.
10 IaaS Manager Service
Load Balancer
Install the first instance of the Manager Service and the first instance of the DEM
Orchestrator together on one machine under this load balancer. See Install the Primary
Manager Service and Install the Distributed Execution Managers.
11 Manager Service 1 and
DEM Orchestrator 1
Install the first instance of the Manager Service and the first instance of the DEM
Orchestrator together on one machine under the IaaS Manager Service load balancer.
The first Manager Service instance is active. Only one can be active at any given time.
See Install the Primary Manager Service and Install the Distributed Execution
Managers.
12 Manager Service 2, 3, and
so on
Passive instances for backup only. If the Active Manager Service fails, start the service
on the passive node.
13 Agents and DEMs Install the first DEM Orchestrator on the active Manager Service machine. Install
Agents, DEM Orchestrators, and DEM Workers together or on separate machines. See
Chapter 6 Installing Agents and Install the Distributed Execution Managers.
