Google Cloud Functions with socket.io [closed]

Question

My understanding is that to establish a persistent socket connection using socket.io the Node.js server should be always running. With Google Cloud Functions there isn't an always running Node.js server, so keeping a socket connection alive is not possible.

Is Cloud Run with a running Node.js server the best option to handle multiple socket connections using socket.io ?

Answer 1

UPDATE: From January 2021, GCP Cloud Run supports WebSockets.
