Seperate business and web front for deployment.

Question

Hi All,

We have to do the final deployment of our mvc website which is developed using C# in Visual Studio 2010. Currently our website is been hosted on the IIS test server and is working nicely.
For the final deployment the client has asked for certain specification.

The want the business logic to sit on IIS web server(ie the application server) , this will be behind the firewall. They want to separate the web front which will sit on the DMZ Server which will be visible to the internet.  Can some one tell me how to separate the business logic and the web front to sit on different servers.

Thank you in advance.
