[TYPO3] Typo3 server for virtual domains

This is the default way. You may install the TYPO3 source tree as a shared directory, as described in the install notes. You then create a website based on the "dummy" package and reference (symbolic link) the TYPO3 source which is stored somewhere outside the Web visible tree of directories. This way you share all common files and still have separate directories for your websites. Using this (recommended) setup, you need a dedicated database for each of your website, but you don't need a dedicated database *server* of course.

Not relevant but for the fact that this is a Linux server and as such you may use symbolic links which would be a little bit trickier to do with Windows (it is possible to create hard links but it is not as handy as with Linux)

Not relevant because your database server, which may or not be installed on your webserver does not need any access to "outside" anyway.

Note: I think you were thinking really about a single physical website and multiple root trees for your websites. This might be possible, although I would not try it for offering hosting facilities. You will have problems with admin rights for each tree, allowing installation of extensions for a single tree and so on. Not speaking about once decouple the content of the database to make it independant.

The question should be with "Apache" and the limit is really high I would say.

TYPO3 Built-in security mechanisms

Not part of TYPO3. You may read hard quota support in Ubuntu or this:

Not relevant to this mailing list. However, a few ideas :

* You will have to replicate files: something based on rsync or unisson for instance
* You will have to replicate the database. See master/slave configuration for MySQL or any other DBMS you would use.
