Those mechanisms solve different failure conditions.</p> <p>WebSocket, MQTT, and SignalR assume that a client can participate in a live communication session. FCM is useful precisely when that assumption no longer holds: the application may be backgrounded, its process may not be running, or its persistent connection may have disappeared.</p>
