//get the gcm id
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(context);
String gcmid = gcm.register(SENDER_ID);
//register with the NotificationHub
NativeRegistration r = hub.register(gcmid);

22. //instantiate a new instance of NotificationHubClient
var hubClient =
NotificationHubClient.CreateClientFromConnectionString("<connection string>",
"<hub name>");
//create the json payload for the notification
var payload = "{ "data" : {"msg":"Hello from Windows Azure!"}}";
//send notification via gcm

25. Delivery guarantee and telemetry
Notification Hubs do not provide delivery guarantee.
Telemetry.

26. Scale
Notification Hubs run on a fully parallelized architecture.
Number of devices and latency.
