[AlanHood]

I am looking for confirmation that Esri Maps for SharePoint 2013 utilizes the App Model/is available via the SharePoint App Store. (internal or external) The existing full-trust, SharePoint server-level install will is out of scope for my 2013 migration. My concern is that my users will be unable to Esri Maps for SharePoint on our new platform.

Hi Alan,

I just double-checked with the team on this: For SharePoint Online the answer is yes as it is based on SharePoint apps exclusively. For SharePoint  OnPrem the answer is no.
