How to model vhosts

[vittore]

Hi,

we have a lot of VMs that store vhosts hosting. What is the best strategy to model these informations?
Is it best to store these informations in a custom field (e.g. vhosts) or in service (e.g. HTTP, port 80, vhost header)?
After a test with the custom field, I am now leaning toward the use of services.
