Mobile Services allow developers to easily add features like authentication, push notifications, and structured data storage to mobile apps. The platform provisions a backend in Azure that connects to SQL databases to store app data. It also supports authentication with social providers and provides SDKs to access the service from any mobile platform. Developers can focus on their core app logic while Mobile Services handles common tasks like user management and notification delivery. It offers a free tier that scales up as needs increase.

- 1. Building Connected Apps with Mobile Services Mike Benkovich - @mbenko mike@benko.com
- 2. Session Objectives and Takeaways What is Mobile Services? What are the components? Where to get the tools How to get started
- 3. Why Mobile Services? • Apps are everywhere • Where’s the Data • Who’s using it • Minimize custom code • Speed to market
- 4. Where does it run? • Web • Windows • Android • iOS • Windows Phone • etc… Data Svc Data Identity
- 5. Connected Patterns • Create a Data Store • Add services • Host it somewhere • Make it work Data Svc Data Identity
- 7. Scenarios • Modern Mobile Applications Windows Store, Windows Phone, iOS, Android, HTML • Common Scenarios Reduce the friction and work required by providing solutions to patterns to work with authentication, push notification, structured storage and more • Rapid Development Provision and deploy solutions in minutes rather than days or weeks
- 8. What is Mobile Services?
- 9. To get started… • Windows Azure subscription • Database for storing information – SQL Azure for rapid provisioning and deployment – Dynamic Schema • Service configuration and scaling – Scripting on data – Identity and notifications • SDK to enable identity and notifications
- 11. Code to instantiate Mobile Services • In Application object add code to create an instance of your Mobile Service • Call methods to operate on the service…i.e. public static MobileServiceClient MobileService = new MobileServiceClient( "https://demoapp123.azure-mobile.net/", "OxxAAAAbbbCCCCCddEEEfffGGGh12345" ); private void ButtonSave_Click(object sender, RoutedEventArgs e) { var todoItem = new TodoItem { Text = TodoInput.Text }; InsertTodoItem(todoItem); }
- 12. Storage • SQL Database partitioned by schema – Appx.ToDoItem – Appy.ToDoItem • Manage data by standard SQL tools – SQL Management Studio – Portal – REST API – CLI Tools
- 13. Work with SQL • Tables created in portal • Dynamic SQL Enabled • Create poco classes and persist as tables
- 15. Identity • Use existing identity providers like Oauth – Microsoft, Twitter, Facebook, Google, etc. • Authorize to work with data • Table options – Everyone – With application key – Authenticated users – Admins
- 16. Add code to trigger authentication private MobileServiceUser user; private async System.Threading.Tasks.Task Authenticate() { while (user == null) { string message; try { user = await App.MobileService .LoginAsync(MobileServiceAuthenticationProvider.Facebook); message = string.Format("You are now logged in - {0}", user.UserId); } catch (InvalidOperationException) { message = "You must log in. Login Required"; } MessageBox.Show(message); } }
- 18. Server logic • Scheduled jobs • Notification services • Diagnostics, logging and scale
- 19. Diagnostics, Logging and Scale • Diagnostics – API calls – CPU Time – Data Out • Logging – console.error(…) – console.log(…) – … Scale - Compute Scale out instance count Scale up VM size Scale - Storage Scale out mobile service tenant to dedicated SQL DB Scale up SQL DB
- 20. Pricing during Preview reserved mode service level agreements Preview No availability SLA* General Availability 99.9% Private VM - Small instance is the only size available Free - unlimited inbound data. 165MB outbound data/day, excess charged. Pay - SQL Database, Compute same reduced rate as Web Sites i.e 33% discount, excess outbound transfers starting at $0.12/GB Up to 100 applications shared mode

Editor's Notes
- #20: Slide Objectives:Detail what Mobile Services provides as far as Diagnostics, Logging and Scale is concernedSpeaking Points: Note when moving a Mobile Service from a multi-tenant DB to its own. Currently data is not automatically migrated.
- #21: Notes:More Details here - http://www.windowsazure.com/en-us/pricing/details/#header-0 SLAWhile Mobile Services is in preview, it can be used with apps in production, if customers ask for SLA and support, both can be provided by the product team upon request as part of the early adopters program, contact zumosla@microsoft.com for details.
