SharePoint top web site always created on Application server

Hello, 

I have installed SharePoint 2013, running on 4 servers(Database, Application, 2 X Front-end). The servers are connected in a farm.

I tested creating a web application, and it works. 

The problem is, in SharePoint 2007 when i created the web application it deployed the files on the Front-End servers and not the Web application server(C:/inetpub/wwwroot... folder). 

In SharePoint 2013 the applications are deployed on the Web application server and not the front ends.

Do You have an idea what i am doing wrong?

Thank You,
