I believe it's stored in the edge gateway internal historian. I have never installed a SQL server on an Edge gateway.
The edge app can be modified using any machine, as long as it's connected to that box - the same way that I can launch the designer on any machine as long as it's connected to any other Ignition server that contains the project I want to edit.
There are gateway administration modules that again, I've not used, but I think it can manage things like backups of edge nodes.
I've only ever used Perspective for edge panels, because that's what I use across the board now, but I believe you can use Vision if you prefer. From what I gather it's an either/or - you either develop in Vision and get 1x local client and 1x remote client, or you develop in Perspective and get a two-session license.
