We recently upgraded our ArcGIS enterprise server to the full ArcGIS Portal environment (data store, web adaptor, server and portal). What I'm struggling with is how best to use Portal. In the past, I have always published feature classes for online maps to AGOL. If those feature classes were updated by field editors, I would periodically manually sync them with the local copy of our data.
As explained to me, the main benefit of Portal is that is allows you to publish your data from your enterprise servers to the portal. You can then add it to a web map, and it syncs immediately. As the field workers make edits, it should update in the enterprise database as well.
That sounds great, but the first part that confuses me is that portal seems to be completely disconnected from ArcGIS Online. We have about 70 users in our AGOL setup, so it will be extremely inconvenient to have to move all of our users from AGOL over to portal. Is there a way to pass services published to portal into AGOL, so that AGOL users can make edits to data in our portal?
The next area I don't understand is how best to manage content published to the portal. Our Enterprise was configured using a single-machine base deployment. The guy that help us set it up told me that he would recommend limiting the number of services published to portal. He said that if too many people started hitting the services at once, and you had a lot of services, it could cause performance problems. How can I figure out how many services I can optimally publish at a time?
Building on that, how best should I publish services? We have around layers on our enterprise database, and of those, it would be helpful to have at least 60 of them published to Portal because they are regularly edited in the field. Should I publish each of those 60 services indidually? Or should I group them into one large service. Or is there an answer somewhere in between there?
Ultimately, my problem is that I can't figure out best to implement portal while respecting our current hardware system specs. I love the features promised by portal, but I want to make sure I implement it in the right way.
