I want to host a Drupal 7 site that effectively has four different silos of information. The architecture will look like this:
- example.com - Blog site with content about the parent company
- example.com/foo - Informational site about sub-company "foo"
- example.com/bar - Informational site about sub-company "bar"
- example.com/fubar - Informational site about sub-company "fubar"
The top site will pretty much be a blog with navigational elements directing people to the sub-sites. The three sub-sites will essentially be the same structure, but have slightly different CSS (different color schemes) and have different information. Logins can be separate, because we actually want to be able to peel away one of the subsites to sell as an asset, if need be.
I'm wondering what the best way to do this would be. Multi-site should keep it easy to update, because the modules and core should be upgraded in lockstep. However, I can't seem to get multi-site to work for these subpaths.
Is multi-site the best way to go here? Or should I just host four different instances of Drupal, one for each site?
(Note, I saw a question about subsites just after I posted this, but it seems that subsites is only available for Drupal 6. Please correct me if that is wrong!)
