There are several ways how this can be done and it sort of depends on
how you want to or need to use the Vsite.

Say you have a fairly static Vsite without email usage. The contents of
/web and the MySQL database contents of it may have fluctuations. In
that case you can just ignore CODB and can clone the Vsite to multiple
BlueOnyx servers and use load balancing via a frontend. If you clone
/web via glusterfs or old fashioned RSYNC via cronjob doesn't matter.
The MySQL database table can easily be kept current with MySQL database
replication.

That would take care of that.
