I am trying to build a multi teir archetecture and seperate out the web server, application server and database into seperate tier that will reside on distinct virtual networks with minimal ports open between the tiers.
Does anyone know how you can seperate PHP so that a webserver catches the request then parses it to the application server, who in-turn talks with the database.
The goal is that there is no direct access from the first tier (web server) to the database.
Thanks
Dan
