This document discusses using Windows Azure Mobile Services to store and access data from Windows Phone apps. It provides an overview of Windows Phone 8, cloud computing on Windows Azure, and how Windows Azure Mobile Services can be used to enable mobile apps to leverage cloud storage, authentication, push notifications, and more. It also demonstrates how to access data through REST APIs and use server scripts for additional functionality and authorization.

9. Azure Mobile Services

10. Client Support
 Official SDKs
 Windows 8, Windows Phone 8
 Android and iOS

11. Application Key
 NOT A SECURITY TOKEN/CONTROL
 Hint that user is coming from your app (reduce chance of misuse)
 Private until you publish the app
Master Key
 All powerful
 Do NOT distribute with your application
 Use from server-side logic you control
Security

12. Leverage strengths of Windows Azure SQL Database
 New or Existing Database
 Reporting, TSQL support, existing tools, etc.
 Manage your way (portal, REST API, SSMS, etc.)
Partition applications by schema
 App1.Users
 App2.Users
Dynamic Schema Support (on/off)
Data Storage

13.  REST API
 OData Interface
 GET, POST, PATCH, DELETE
https://<service>.azure-mobile.net/tables/<table_name>/{<item_id>}
Authorization
X-ZUM0-{APPLICATION | AUTH | MASTER}
Send JSON in request body
Receive JSON as response
Data Access

14. Microsoft Account – Use the Live SDK
Tight integration with Windows Live services
Authentication

15. Microsoft Account, Facebook, Twitter, and Google
OAuth
Does not use Windows Azure ACS
Authentication

16. Table level authorization for CRUD operations
Everyone: any request by anyone is accepted.
Anyone with Application Key: app key distributed w/ the app (default)
Authenticated Users: users authenticated by Live Connect.
Scripts and Admins: registered scripts or requests via the master key
Your application can add whatever other authorization is needed.
Authorization

17.  Server script to match against your table (role-based access, specific user, etc.)
 Match against user.userId
Authorization

18. PUSH Notification

19. Execute scripts on a Schedule
 by minutes / hours /days /month
Execute scripts on demand
Examples
 Periodic purge of old data
 Poll and aggregate from 3rd party (Twitter, RSS, others)
 Process/resize images
 Schedule sending push notifications for a given time of day
Scheduler

20.  API Calls
 CPU Time
 Data Out
