What function does the ArcGIS Web Adaptor serve?

The ArcGIS Web Adaptor plays a crucial role in seamlessly integrating ArcGIS Server with an organization's existing web server infrastructure. This integration allows for a more secure and efficient deployment of web mapping applications and services. By acting as a bridge, the Web Adaptor routes requests for GIS services through the organization’s web server, leveraging its existing security configurations, such as authentication and authorization.

This function is particularly important in enterprise environments, where maintaining a cohesive IT structure is critical. It helps to simplify this setup by allowing ArcGIS Server resources to be accessible without necessitating considerable changes to the web server architecture. Consequently, users can access geospatial content in a familiar web context, further enhancing the usability and reach of the GIS capabilities within the organization.

In contrast, the other options focus on features not directly related to the Web Adaptor's primary function. Creating interactive maps, managing databases, or generating reports represents distinct components of GIS functionality rather than the specific integration role that the Web Adaptor fulfills.
