vCAC 6: Installation Pre-requisites

Now we will discuss installation of vCAC 6.

Installation Pre-requisites:

vCloud Automation Center can be deployed in two Configurations:

  1. A minimal installation is the deployment of a single instance of each vCloud Automation Center component.
  2. distributed installation  installs multiple instances over separate servers for scalability, redundancy, high availability, and disaster recovery

vCloud Automation Center consists of the following components:

  •  Single sign-on (SSO) server : VMware Identity Appliance or VMware vCenter 5.5 U1 SSO
  • vCloud Automation Center appliance
  • VMware infrastructure as a service (IaaS)
  • Distributed Execution Managers (DEM)
  • Agents
We need to follow the below flowchart if we want to implement VCAC successfully

A vCloud Automation Center Appliance stores data in a PostgreSQL database. The default installation creates the PostgreSQL database locally but an administrator may install it on another server

The IaaS server supports the following database platforms:
Microsoft SQL Server
• SQL Server 2008 R2 SP1, SQL Server 2008 R2 SP2
- Enterprise, Standard, Express
• SQL Server 2012, SQL Server 2012 SP1
- Enterprise, Standard, Express
IaaS server database connectivity requirements:
TCP/IP protocol enabled for MS SQL Server
Microsoft Distributed Transaction Coordinator Service (MS DTC) enabled on all SQL nodes in the system Appropriate network ports open between Database Server and IaaS Server
If using SQL Server Express, the SQL Server Browser service must be running.


Identity Appliance ingress ports
Identity Appliance: Egress Ports

the remaining ports are

Now we need to determine compute requirements

component CPU Memory  Storage
Identity Server Virtual Appliance  1 2GB  2.5GB
vCloud Automation Center Appliance  2 8GB 30GB
IaaS Server  2 4GB 30GB
ITBM Standard  2 4GB 16GB
Application Director  2 4GB 16GB

Now we would need to determine IAAS service  manager requirements

The IaaS Manager Service requires the following:
  • .NET Framework 4.5 must be installed
  • Microsoft PowerShell 2.0 (included with Windows Server 2008 R2 SP1 and later) or Microsoft PowerShell 3.0 on Windows Server 2012 must be installed. SecondaryLogOnService must be running. Appropriate network ports between DEM host and Windows Server should be open.
We would also need to determine credentials for access.

vCenter service account A domain or local account is needed for endpoint access
Virtual appliance installation Administrative privileges on the deployment platform are required
IaaS installation The user that executes the installation should be a local administrator
IaaS database credentials The user must have IaaS database owner privileges
IaaS service user credentials The user must be a domain user and have local administrator privileges
on all systems with installed IaaS components

Now we are ready for Installation.
