I am using ArcGIS for Server 10.2.2 with SQL Server 2008 R2.
I am running 80 Map and Geoprocessing Services.
So far, there have been no performance issues. The WebMaps I have created using the Local Layer Widget (all hosted internally, not using AGOL) work fantastic.
But, i keep getting requests for "more please".
How many Services can be run from ArcGIS for Server? is there a limit?
