I am building a web application, and the specification is to use three tier architecture.
My requirements are a general 3 tier application where the presentation layer had to be on one server, the application code (in this case it was business logic and data access) on a second server, and the database on the third server, and the first and third servers should never communicate with each other, but had to go through the middle app server.
Does anyone know if i can use the cms concrete5 to perform this task, as it is an integral part to my general workflow. I know that it uses a 3 layered application architecture but not too sure if i can convert this into a 3 tier application?
if anyone has any insights to how this could or has been done on drupal or wordpress that would be appreciated?
