    Web sites are a core entity of IIS that determine where and how requests
    will be handled. The web site API allows consumers to create, read,
    delete, or update their web sites.
- name: Applications
  description: >-
    Applications provide a method to differentiate sections of a web site.
    An application belongs to a single web site and will handle requests
    for the web site at the application path.
- name: Application Pools
  description: >-
    Application pools provide an isolation mechanism for processes on the
    web server. There are many different settings available to fine-tune
    the behavior of the worker processes used to serve requests through IIS.
