FCM + App Server(XMPP) at Google App Engine? (GAE)

[이재학]

Is it possible to use XMPP server at Google App Engine(GAE), to use FCM(GCM)?

[Silvano Luciani]

Hi,

You could use it only to receive upstream messages from the devices, not to send downstream messages to the devices, and even in that case, you'd need to send the message to "SEND...@appspot.com" rather than "SEND...@gcm.googleapis.com".

The other thing to take into account is that you'd need to use manual scaling on AppEngine, because you'd need a long running process.

For long running processes he can use tasks, keeping automatic scaling
