The Extensible Web Platform
The Windows Server 2008 R2 Web Server (Internet Information Services, IIS 7.5) is built with a completely modular architecture on top of rich extensibility APIs. This enables developers to easily add, remove, and even replace built-in IIS components with hand-crafted ones specifically suited for any given Web site. It is now easy to plug code deep into the IIS core pipeline and extend IIS in ways that were previously impossible. In addition to exceptional modularity and extensibility, the Web Platform enables a myriad of Web Development scenarios including ASP.NET, PHP, FastCGI, Web Services, improved FTP services, as well as integrated media solution scenarios. New Modules, Extensions, and Utilities are published regularly online. For example, the new Web Platform Installer (WPI) utility enables seamless deployment and configuration of the Microsoft Web Platform, including IIS, SQL Server Express, .NET Framework and Visual Web Developer, as well as custom extensions and reusable application-templates from the online Web Gallery.
