Application and data server

[Julien-Samuel Lacroix]

Hi Artur!

This is a tricky one. It really depends on the trafic you have on your 
website. For a moderate trafic website you only need a basic 
installation. One server with MapServer + PostGIS + Application.

However if you get too much traffic for a single server, you may want to 
separate the Application and MapServer. MapServer is usually what takes 
the most ressource of a server. This is more true when it is poorly 
configured. So before doing that, make sure you have tuned your data, 
mapfile and server. The first things you should check are removing the 
PROJECTION blocks and the filters (For any other advice ask the list). 
Other than that, there's no real problem to put the database and 
MapServer on the same machine I think.

In the case you decide to separate PostGIS and MapServer on 2 different 
machines, you don't need to use WFS or WMS. You can connect to PostGIS 
like usual I think.

Best regards,
Julien

PS: There's information in the wiki about security issues.
