Here's what I'm doing and you experts can tell me where I'm at.

I want to use Azure to host a few sites.
I want to use DNN for all of those sites.  Say 10-20 sites.
Playing about testing on Azure I've come at it a couple of ways.

1>
Setup a database, installed a DNN site (Red), then installed another site (Blue) to the same database using Object Qualifiers (BM).  <<< So 2 DNN installs on to 1 database.   This works but I have a suspicion it's not the right way to go.  The database would soon have zillions of tables with each Object Qualifier.

2>
Using a portal:  On the Blue install using the host/site management I added another site Green but this doesn't work (yet).  My spidey senses tell me that I should set up another alias on Azure and point to Blue but I'm not clear on this, if it's right or how to do it.

Any pointers greatly appreciated. :)
