Because we use ArcGIS Online Web Maps in our daily work-flows, I created an AGO group that contains Feature Layers that are links to our self-hosted ArcGIS Server services. This way, users can quickly add data from our ArcGIS Server Site and not have to look up URLs/Usernames/Passwords (I’ve save the username/password as part of the ArcGIS Online service when appropriate). But I’ve had a problem where if I change the service, the changes are not reflected in the AGO Feature Layer for that service and I have to monkey about to get the changes to migrate to the maps.

I’ve seen several posts like this one that reiterate that ESRI has announced that: ‘As of the end of January, ArcGIS Online basemaps published and hosted by Esri are now freely available to all users regardless of commercial, noncommercial, internal, or external use. This means that you no longer have to pay a subscription fee for including ArcGIS Online basemaps in your commercial-use web applications. Basemaps included in this new business model are World Imagery Map, World Street Map, World Topographic Map, USA Topographic Maps, and DeLorme World Basemap.
