Our organization is currently using ArcGIS Server 10.3 and we serve up maps within our organizations intranet using Geocortex. Currently I am configuring the newest version of Geocortex and wanting to be able to add map layers so our users can have additional content. To do this our server needs to be registered with ArcGIS Online. Can someone direct me on how to register our server with ArcGIS online? We have an ArcGIS Online account. Also, can someone tell me, is there a charge for this?? I am baffled!
Thank you in advance for any direction you can provide,
