What is the primary function of ArcGIS Server within ArcGIS Enterprise?

The primary function of ArcGIS Server within ArcGIS Enterprise is to publish and manage services for web applications. This means that ArcGIS Server enables users to create and share various types of GIS resources, such as map services, feature services, and geoprocessing services, making them accessible to web applications and users through REST APIs or other protocols. By doing so, ArcGIS Server acts as a central hub for managing and delivering GIS content, allowing organizations to distribute geospatial information efficiently and effectively to various end-users.

This capability is crucial for creating interactive web maps, enabling data visualization, and providing access to geospatial analysis tools within organizations. The focus on publishing and managing services distinguishes this function from other components in ArcGIS Enterprise, which may deal with data storage, user authentication, or analytical tools.
