ArcGIS Server, everything it used to be and more
ArcGIS Server is part of ArcGIS Enterprise and now it can do more than ever. License your ArcGIS Server as a traditional GIS Server or take advantage of one of the four new licensing roles: Image Server, GeoEvent Server, GeoAnalytics Server, or Business Analyst Server.
ArcGIS Enterprise is supported on Windows and Linux and has flexible deployment options for both physical and virtualized environments, connected or disconnected from the open Internet.
