Microsoft Internet Information Services (
IIS) is Microsoft’s secure web server platform for hosting web based services and applications. It was formally known as Internet Information Server, but is now renamed as a service to reflect that it can be hosted on several types of Windows Server from the Nano version and up. IIS deployments on a par with Apache, but the latter has more active deployments by a wide margin. IIS is used for a lot of deployments that use the Microsoft toolset to develop applications.
