How a research project forced Microsoft to build its own web server
In short: Microsoft's first web server was a freeware research project at the University of Edinburgh. However, it struggled to manage the massive traffic surge to Microsoft.com, forcing the tech giant to develop a dedicated, extensible solution: Internet Information Services.
Internet Information Services (IIS) has become a cornerstone of the Windows NT family, evolving through numerous iterations since its early days. The process started because the initial research undertaking at the European Microsoft Windows NT Academic Centre (EMWAC) could not manage the massive amount of traffic hitting Microsoft.com. This need drove the development of IIS, which launched as a free extension for Windows NT 3.51 via version 1.0.
The evolution of IIS is marked by significant architectural shifts and security refinements. Early versions faced criticism regarding licensing; for instance, the Windows NT 4.0 Workstation edition was limited to ten simultaneous TCP/IP connections, a distinction Netscape argued had no technical merit and was intended to drive users toward the more expensive Server edition. By IIS 6.0, Microsoft introduced a new worker process model to enhance security and reliability, and required components like ASP to be explicitly installed to prevent hackers from exploiting unused features.
Modern iterations have focused on performance and modularity. IIS 7.0 represented a complete redesign and rewrite, introducing a modular architecture that allowed administrators to install only the necessary modules, thereby reducing the attack surface. Later versions, such as IIS 8.0, introduced features like Server Name Indication (SNI) to bind multiple websites to a single IP address via hostnames. Today, IIS 10.0 supports advanced protocols like HTTP/2 and HTTP/3, providing the robust infrastructure required for contemporary web services.
