I have a set of feature classes in our organization that I wish to publish to ArcGIS Online. I need to be aware of the Data Storage Credits that will be consumed in ArcGIS Online for the storage of these feature classes as hosted feature services. I am noticing that the amount of data storage for a given feature service in AGOL is on the order of 2.8 times greater as compared to the amount of disk space consumed in a File Geodatabase. For example, I have a feature class that requires 38 Mbytes in a File Geodatabase and 88 Mbytes in a Personal Geodatabase. When the same feature class is published to ArcGIS Online as a feature service, the amount of data storage required is being reported as 106 Mbytes.
If one has their set of feature classes in a File Geodatabase, is there a method of estimating the amount of data storage needed to store these same feature classes as feature services in ArcGIS Online?
