Installing VMware vCloud Automation Center is strongly recommended for the beautiful things that administrators or tenants can do. An example is deploying popular big data clusters using a very simple procedure (I will post a how-to soon for this). There is a perfect and comprehensive 7-part installation, configuration manual written by Kenny Coleman which can be found here.
So, if you didn’t deploy vCAC in your management environment yet, install and you will enjoy it!

p.s – I found Part 3 (Installing IAAS) of this guide the most difficult one. There are some hints that I would like to add:

• To ease installation, don’t use external MS SQL server. Instead, install SQL Express 2012 on the same Windows machine (IAAS and Model Manager Server).
• Make sure that DNS settings are correct and IAAS Server FQDN can be resolved.
• If you don’t use Active Directory, YOU MUST specify domain name in Primary DNS suffix of System Properties to make computer full name like its FQDN. It’s very important that in Step 8, Current Server filled automatically with FQDN and not Stand-Alone Server name. Domain should be there. Or you will face with an error (in Logs) like:
  “Building Project “C:\Program Files (x86)\VMware\vCAC\Server\Model Manager Data\DeployRepository.xml” (VARegistrationFinalSteps target(s)) — FAILED.
  Build FAILED.
