A GIS contractor is developing and testing an upcoming workflow for a client.

The contractor should publish a hosted feature service. Hosted feature services are managed entirely by the ArcGIS Data Store, not by the ArcGIS Server site directly. This means they consume fewer server resources since they are not managed by a dedicated ArcGIS Server site’s memory or CPU at runtime the way traditional services are.

From ArcGIS documentation:

“Hosted feature layers (services) are stored in and powered by the ArcGIS Data Store, relieving ArcGIS Server from managing service processes. This is ideal for testing, lightweight apps, or non-production workflows when minimizing load on the GIS Server is desired.”

Option B (Non-hosted map service) would require server-side management and is more resource-intensive.

Option C (Scene service) is used for 3D visualization and is not appropriate for 2D hydrant location data.

Option D (Non-hosted feature service) would also consume more ArcGIS Server resources.
