Where To Place A Web Application Server - 2.Dec.2008 7:34:14 PM

I have a C#.NET, .NET 3.5 web app running on a Windows 2008 box that requires access to AD, calls business services on a back-end server via SOAP and DCOM, and I would like to make it accessable from the Internet.

I already have a back-to-back firewall configuration with a DMZ that has private addresses, although the front firewall is not ISA. Split DNS has been implemented, with the public DNS server in the DMZ not being a member of the AD domain.

The choices I see are either to place the web server in the DMZ and apply rules to the back-firewall ISA server to allow SOAP, DCOM, AD traffic, et.al., or to place the wep app server on the internal network and publish it to the DMZ using the back-firewall ISA server.

I believe the second choice is preferred, but what are the pros and cons of each?

I will go with the second one as well because i would not want to open so many ports on my back-end firewall if i can work it from internal...

Thank you for the reply. I was leaning that way as well, but I wasn't confident enough in my understanding of the server publishing rules in ISA server to make a firm decision.

This leads me to think of the future, where I will eventually have 5 web application servers being published through the ISA Server.

Are there any articles about the performance of ISA Server in a publishing capacity based on the number of concurrent connections?

And of course, there is the imminent release of ForeFront TMG in 2009. Can that be used in the same role?
