A site is a collection of server resources. This collection includes server machines
that are installed with ArcGIS for Server, including GIS services, data and so on.
The site resource also lists the current version of the software.
When you install ArcGIS for Server on a server machine for the first time, you must create a
new site. Subsequently, newer server machines can join your site and increase its computing power. Once a site is no longer required, you can delete the
site, which will cause all of the resources to be cleaned up.
The site maintains all its configuration and meta information on disk in a set of files that make up the
Configuration Store.
