Alexander Brown I am still wondering - is this really possible? And Like geoshi asks, I want MapServer map image service end points. What you described, was basically we don't need AGS Enterprise on prem, just the data. And then we can 'publish' to AGOL instead of our on-prem AGS Enterprise Server? That sounds... too good to be true?? Anything to take the load off my server I am interested in. AGS just seems not to be able to handle a heavy load. I literally just put my parcel and address data on to AGOL as a feature layer to attach the Search widget to, because the request traffic was killing my server. (I fiddled with pooling, service timeout, recycling the service hourly, aggressive draw scales, separating heavy annotation layers into separate services, etc. And the AWS instance does only this one site but it could have dozens of simultaneous requests. 16 GB RAM but it could not handle it for some reason. The 'suggest' in particular seems to have buried it in traffic and it could not do it. So I put the data on AGOL now it works great. ) Reason I ask is... there is no such thing as a 'Hosted' locator. https://community.esri.com/message/888896-re-composite-locator-not-properly-locating-address-points?... ArcGIS Online Hosted Locators I want to get a Locator that works with Units and Suggest (still not a thing.... ) but I would settle for a Hosted Locator and perhaps Hosted data, if an on premise AGS server can't handle traffic. (Either it can't handle traffic or I don't have it configured efficiently but I've spent a lot of time testing and configuring to no avail)
So, that all seems like a long story. Bottom line is, my sites run slow under load. Operational layers load slowly, Locators work slowly, and Suggest barely works at times. Well, Suggest works fast now, but because I put the layers on AGOL and Search widget now searches it as a featureLayer. I would prefer however to have a Locator to search Owner Name in our Parcel layer because it is more flexible with the spelling (vs searching directly as a featureLayer). So... here is what I would like to do. Publish a Locator to AGOL that points at my on-prem SDE data.
