ArcGIS Enterprise is a mapping, analytics, data hosting, and content management product that can be hosted on-premise or in your infrastructure. It can be used to create, share, and manage maps, scenes, layers, apps, services, and other geographic content; it is a secure way to access data and functionality such as geocoding and routing through web services; and provides access to unique ArcGIS basemap and layer data. Typically, this content is stored securely and managed with ArcGIS Online. ArcGIS Enterprise can be used in tandem with or in place of ArcGIS Online. ArcGIS Enterprise is composed of a portal, a server, a data store, and an ArcGIS Web Adaptor. These provide the backbone for Esri's suite of applications and also support any organizational, customized applications.
