Hardware scenarios

There are several ways that ArcGIS Enterprise can be deployed. These range from simple single-machine deployments to more complex multi-machine scenarios. Prior to ArcGIS Enterprise 10.5, a base deployment consisted primarily of ArcGIS Server and the ArcGIS Web Adaptor. At 10.5, a base deployment consists of the four main components of ArcGIS Enterprise--ArcGIS Server, Portal for ArcGIS, ArcGIS Data Store, and ArcGIS Web Adaptor, all working together.
