When seeing the Windows Server 2008 R2 edition comparision by Role, i noticed that there is an entry for Application Server separate from that of IIS. http://www.microsoft.com/windowsserver2008/en/us/r2-compare-roles.aspx
What is confusing me is that for Web edition, "Application Server" is not ticked but IIS is ticked.
Isnt IIS both the web server and the application server in Windows? And if so, if i take the web edition, can i not host my business components (WCF services)on it because it is not an "Application Server" ?
