We have hosted a number of datasets as feature layers in ArcGIS online as we expect a 1000's of hits to our web application when we launch as it is being used for a public consultation for a number of weeks.
Our clients have requested that they can search by different fields in our datasets which we can do using the geo coding service widget in our web app using our feature layers.
One thing we are not quite clear on is about how much credit usage the geocode widget will use. I have seen 40 credits per 1000 geo codes which I assume means 1000 search for 40 credits against our feature services.
One thing we have wondered is if we host the data on our servers would we get around the credit charge for the geo coding and the data not being stored in the cloud. As the processing would be done our servers but still using the geo coding widget?
