Microsoft is the primary creator and owner of Internet Information Services (IIS) , which is a proprietary extensible Internet Information Services (IIS) web server software package designed for the Windows Server ecosystem.learn.microsoft.com [learn.microsoft.com](https://learn.microsoft.com/en-us/lifecycle/products/internet-information-services-iis)[[2](https://www.solarwinds.com/resources/it-glossary/iis-server)](https://www.solarwinds.com/resources/it-glossary/iis-server)

If you are referring broadly to major global companies that provide core internet information, cloud hosting, and web infrastructure services rather than the specific Microsoft IIS software product, the industry is led by major technology and cloud conglomerates:

• Amazon: Operates Amazon Web Services (AWS) , the world's largest cloud infrastructure platform that hosts and serves vast amounts of internet data and web applications.
• Google (Alphabet): Dominates internet content, search, and information indexing, while also providing enterprise cloud and infrastructure services via Google Cloud Platform.
