[postgis-users] ArcGIS Online without ArcGIS server

[Regina Obe]

This may be a question to just people using ArcGIS Online or at least
familiar with it.  Is it possible to have an ArcGIS online connect to a
PostGIS enabled database (assuming you have the port open etc), without an
ArcGIS Server license?
If so are their limitations in terms of what features you can use of ArcGIS
Online like their javascript apis etc?

Thanks,
Regina
