It’s a bit a stretch, but is there a way to target a specific instance using DNS, or even a magical querystring parameter?
I can make it work by creating an app for each region, but that seems rather wasteful (considering each app gets an IPv4).
The motivation for the question is that I’m building a minimal single process websocket server, where the messages are only passed around to clients connected to the same server.
Thank you! That’s extremely useful information (I’m sorry I didn’t find those threads myself). Running a single app, with single instances in each region (with an assigned regional IP) seems like the best bet for me.
