Mobile Services .NET backend • ASP.NET WebAPI based • Custom API Regular ApiController • Table API XXXTableController • Helpful ODATA CRUD abstractions over various data backends • Transparent data access • Built-in auth, authz, push, monitoring, etc. • Client SDKs work with Mobile Services Node and .NET backends • We run, manage, and monitor your Mobile Service
Source Control and Deployment Mobile Services (git repository) TFS or GitHub (git repository) Local git repository
Automation npm install azure-cli --g azure mobile create | delete | list | show azure mobile restart azure mobile config list | get | set azure mobile table | data azure mobile script | api //use source control instead azure mobile job
Unit testing Node.js: var mock = require(“zumock”); //inspired by mocha .NET: NUnit, MSTest, etc Local F5, local debugging
Add version to your client calls - (void)handleRequest:(NSURLRequest *)request next:(MSFilterNextBlock)next response:(MSFilterResponseBlock)response { MSFilterResponseBlockwrappedResponse = ^(NSHTTPURLResponse *innerResponse, NSData *data, NSError *error) { response(innerResponse, data, error); }; // add additional versioning information to the querystring for versioning purposes NSString *append = [NSStringstringWithFormat:@"build=%@&version=%@", self.build, self.version]; NSURL *url = nil; NSRange range = [request.URL.absoluteStringrangeOfString:@"?"]; if (range.length > 0) { url = [NSURL URLWithString:[NSStringstringWithFormat:@"%@&%@&p=iOS", request.URL.absoluteString, append]]; } else { url = [NSURL URLWithString:[NSStringstringWithFormat:@"%@?%@&p=iOS", request.URL.absoluteString, append]]; } NSMutableURLRequest *newRequest = [request mutableCopy]; newRequest.URL = url; next(newRequest, wrappedResponse); }
Add version to your client calls public static MobileServiceClientMobileService = new MobileServiceClient( "https://<your subdomain>.azure-mobile.net/", "<your app key>", new VersionHandler() ); using System; using System.Net.Http; using System.Threading.Tasks; namespace WindowsStore { public class VersionHandler : DelegatingHandler { protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, System.Threading.CancellationTokencancellationToken) { request.RequestUri = new Uri(request.RequestUri.AbsoluteUri.ToString() + "?version=v2"); return base.SendAsync(request, cancellationToken); } } }
Support multiple client versions in your scripts function insert(item, user, request) { if (request.parameters.build < 2.0) { item.description = 'Not entered'; } request.execute({ success : function() { if (request.parameters.build < 2.0) { delete item.description; } request.respond(); } }); }
Mobile Push Notifications 101 • Register device handle at app launch • Client app contacts Platform Notification Service (PNS) • App updates handle in backend client app • Send Notification • App backend sends notification to PNS • PNS pushes the notification to the app on the device Platform Notification Service • Maintain device handles • Delete expired handles when PNS rejects them App back-end
Push Notification Challenges While there are significant benefits to using push notifications in a mobile app, rolling your own push infrastructure is extremely difficult in terms of implementing a system capable of: • Cross-Platform Push Notifications Each push service (APNS for iOS, GCM for Android, WNS for Windows, etc.) has different protocols (e.g., HTTP vs. TCP, xml payload vs. JSON payload) • Targeting on the server-side based on interest and location Segmenting users based on interest tags and routing only the most relevant content to each segment • Personalizing notifications on the client-side based on language, currency, device, etc. Each device displays notifications differently • High-Volume with Low Latency Limited by the capability of each VM so need to spin up scores of VMs and shard your application in order to serve a large user base • Maintaining and accurate device handle registry Adding registrations upon installation, updating tags, pruning upon rejection from push notification service (uninstall)
Azure Push Notifications One-time set up Create a Notification Hub Register The client app retrieves its current handle from the PNS. Client app (or app backend) registers the handle with Notification Hub Send Notification The app back-end sends a message to the Notification Hub. Notification Hub pushes it to the PNS Android app iOS app Windows 8.x app Notification Hub App back-end WNS APNs MPNS GCM
Mobile Services + Notification Hubs Mobile Services now with Notification Hubs built-in • Cross-Platform Push Notifications • Instant broadcast to segments of your audience, or individual pushes to logical users • Personalization and localization • High-Volume with Low Latency • Device handles and PNS feedback is managed for you

Tips for Actually Publishing to the Store • Dev/Test Instance • Switch to using prod keys and info incl APNS cert, GCM API key • Make sure the permissions are as locked down as possible/access as restricted as possible • Turn off dynamic schema • Verify parameters, checking userIDs on all methods. • Authorization needs to be done in app code • Put in perf metrics (New Relic) • Put in usage metrics (Google) • Don’t put demo in the description • Have all the right assets • Get out of free mode • Auto-Scale
