Internet Information Services

Internet Information Services, also known as Microsoft IIS (or shortly IIS), is an extensible web server created by Microsoft for use with the Windows NT family. It has been an integral part of the Windows NT family since Windows NT 4.0, though it may be absent from some editions (e.g. Windows XP Home edition), and is not active by default. 
==Features ==
IIS supports HTTP, HTTP/2, HTTP/3, HTTPS, FTP, FTPS, SMTP and NNTP, and has a dedicated suite of software called SEO Toolkit"Getting started with the SEO Toolkit" - Microsoft This suite has several tools for SEO with features for metatag and web coding optimization, sitemaps and robots.txt configuration, website analysis, crawler setting, SSL server-side configuration and more.
IIS 6.0 and higher support the following authentication mechanisms:
*Anonymous authentication
* Basic access authentication
*Digest access authentication
*Integrated Windows Authentication
*UNC authentication
*.NET Passport Authentication (Removed in Windows Server 2008 and IIS 7.0)
* Certificate authentication
IIS 7.0 has a modular architecture. Modules, also called extensions, can be added or removed individually so that only modules required for specific functionality have to be installed. IIS 7 includes native modules as part of the full installation. These modules are individual features that the server uses to process requests.
IIS 7.5 includes the following additional or enhanced security features:
*Client certificate mapping
*IP security
*Request filtering
*URL authorization
IIS 8.0 offers new features targeted at performance and easier administration, such as:
* ASP.NET 4.5 supportIIS 8.0 ASP.NET configuation management (29 February 2012)
*Dynamic IP Address Restrictions
*CPU Throttling
*Application Initialization, which is a feature that allows an administrator to configure certain applications to start automatically with server startup. This reduces the wait time experienced by users who access the site for the first time after a server reboot.
*WebSocket Protocol Supporthttps://www.iis.net/learn/get-started/whats-new-in-iis-8/iis-80-websocket-protocol-support
* Multicore scaling on NUMA hardware: Since IIS 8.0, it provides several configuration options that optimize performance on systems that run NUMA, such as running several worker processes under one application pool, using soft or hard affinity and more.
==Application==
The application of Internet Information Services is a feature of Windows NT that can be enabled through turning windows on or off. It is primarily used for Windows Servers. Users can setup any websites with IIS along with modifying web servers, firewall and routers.
