The vCO appliance makes it very easy to deploy vCenter Orchestrator in minutes. My colleague William Lam went a bit further with providing a script that let you pre-define a lot of the configuration settings.
The script leverage the OVF format to set a number of parameters such as the appliance network settings, placement on the virtual infrastructure datastores and network.
You can find out more about it here.
I am looking forward to see more vCO articles from William since he has a very successful VMware scripting blog with a lot of interesting articles. I encourage you to browse it if you did not knew it yet.
