[google-appengine] Re: WebSocket client and auto scaling
Hi, you could use another GAE service with maximum scaling = 1, which would act as a proxy to Discord for a new GAE bot service, which would continue scaling as before. The proxy service would just take the connection functionality from the old bot service and modify it minimally to forward the connections from the new bot service to discord using just one socket, and it shouldn't have much of an issue with workload even if the number of requests is considerable, as it is just relaying the information. The new bot service would have the connectivity logic adapted to this new setting. You could also use a GCE instance instead of a GAE service for the proxy.

[google-appengine] Re: Tasks: Guaranteed delivery time
Hi, as even though Cloud Tasks is not intended for real-time settings, this should not make premature triggering possible, so this looks like a malfunction. I didn't find documentation nor related cases about the premature triggering, either. I recommend you to ask for technical help in Issue Tracker [1].

[google-appengine] Re: Non http/https traffic to appengine
Hello, just to be sure, do you mean you want to ensure that traffic that is non-http (thus, it is https) is not allowed, and that traffic that is https is not allowed? So you mean you only want to allow http, and not allow https? Anyway, there is no default mechanism to do that using App Engine's infrastructure, it has to be done on the code level. Related to this, there is the documentation about forcing https [1]. App Engine has its own firewall, so, no, VPC firewall rules don't apply to it. You can configure its firewall, the documentation is this [2].
