Examples of Internet Information Services

Internet Information Services (IIS) is a web server and a set of related tools designed by Microsoft for managing and serving content on the internet or an intranet. Here are three real-world examples of IIS technology:

E-commerce Websites: IIS is used by many e-commerce websites as their web server to host their online stores and manage user authentication, transactions, and the overall shopping experience. Since IIS supports ASP.NET, a programming framework developed by Microsoft, it allows developers to build e-commerce sites with seamless integration with other Microsoft products like SQL Server and Active Directory.

Corporate Intranets: Companies use IIS to host their internal websites, web applications, and web-based tools such as employee directories, project management platforms, and document management systems. IIS provides a secure environment for these intranets, as it supports various authentication protocols and can easily be integrated with existing company infrastructure. Intranets built on IIS help in better communication and collaboration among employees, leading to increased productivity.

Content Management Systems (CMS): IIS is also popular among developers who use the platform to host web-based content management systems such as Sitecore and Umbraco. These systems allow companies to create, manage, and publish their digital content on the web easily. Since IIS supports Microsoft technologies like ASP.NET, it becomes an obvious choice for developers working with CMS that require Microsoft integrations, ensuring smooth deployment and compatibility with existing systems.
