Microsoft Internet Information Services (IIS, formerly called Internet Information Server) is a set of Internet-based services for servers using Microsoft Windows. It is the world's second most popular web server in terms of overall websites, behind Apache HTTP Server. As of October 2007 it served 37.13% of all websites and 38.23% of all active websites according to Netcraft.[1] The servers currently include FTP, SMTP, NNTP, and HTTP/HTTPS.

Debuting with Windows Vista, and also to be included in Windows Server 2008, IIS 7.0 features a modular architecture. Instead of a monolithic server which features all services, IIS 7 has an integrated mode application pool where .NET modules are loaded into the pipeline using the module API, which allows modules can plug in anywhere in the request processing pipeline. Much of IIS's own functionality is built on this API, and as such, developers will have much more control over a request process than was possible in prior versions. Modules can be loaded globally where the services provided by the module can effect all sites, or loaded on a per-site basis. IIS 7 has an integrated mode application pool where .NET modules are loaded into the pipeline using the module API, rather than ISAPI. As a result ASP.NET code can be used with all requests to the server.[9] For applications requiring strict IIS 6.0 compatibility, the Classic application pool mode loads asp.NET as an ISAPI.
A significant change from previous versions whereby web interfaces, or machine administrator access, were required to change simple settings such as default document, active modules and security/authentication. It also eliminates the need to perform metabase synchronization between multiple servers in a farm of web servers.
