Ok I see. I just tested persisting data to each db and the correct data is being returned when hitting the machines at the different ports so you are correctly routing based on ports. or I am just very lucky today.
It was nice while it lasted. I think we will create a machine per app, clientID-App1, ClientID-App2 etc… machines all at standard https port (not feeling real confident with the non standard ports). The nice part about all customer machines under one app is that billing was easy since you break down our cost by app. From our end users perspective it makes no difference.
In case your wondering these demo machines are all connecting to a planetscale db.
Is there a billing API that return cost break down?
