5. What are we Building Apps for?

6. How can we Build those Apps?
C#, HTML/JS
Java
Objective-C
HTML/JS C#

7. Which should I use? ?

8. Windows Azure Mobile Services
Auth
Server Logic
Notifications
Logging & Diag
Data
Scheduler
Scale

9. Getting started with HTML / JS

10. Structured Storage Powered by SQL Database
Same DB – Multiple Mobile Services
Data management in:
Windows Azure Portal
SQL Portal
SQL Management Studio
REST API
CLI Tools

11. The REST API Base REST API Endpoint URL
Data Operations and their REST Equivalents
Action
HTTP Verb
URL Suffix
Create
POST
/TodoItem
Retrieve
GET
/TodoItem?$filter=id%3D42
Update
PATCH
/TodoItem/id
Delete
DELETE

12. JSON to SQL Type Mappings
JSON Value
T-SQL Type
Numeric values (integer, decimal, floating point)
Float
Boolean
Bit
DateTime
DateTimeOffset(3)
String
Nvarchar(max)

13. Server Side Scripts Customizing data flow on the server
Built on top of Node.js
Intercept CRUD requests to tables
Passes through to SQL by default
Fully customizable logic flow

14. Node Modules Extensibility through numerous modules request push.*
sendgrid
console
mssql
pusher
statusCodes
azure
twilio

15. Adding Server Logic

16. Push Notifications Client Register for push notifications
Mobile Services

18. User Authentication

19. Data Authorization Table level permissions for each operation
Everyone
Anyone with the Application Key
Only Authenticated Users
Only Scripts and Admins
User options in scripts
user.level (admin, authenticated, anonymous)
user.userId (provider:id or undefined)

20. Adding Authentication with Xamarin

21. Command Line Tools Scriptable control from PowerShell / Bash
Create / Delete Services
Inspect / Delete Table Data
Create / Update / Delete Tables and Permissions
Create, / Upload / Delete Scripts
Scale Up / Down Services
Much More!

22. Using the CLI

23. Scheduler Execute scripts on a Schedule Execute scripts on demand
Frequency and length of execution based off of service level

24. Custom API Same permissions as Tables Non-table based scripts
Accessible from:
Get
Post
Put
Patch
Delete
Same permissions as Tables

25. Script Source Control Shared Scripts NPM Handled through Git repo
Access to table, scheduler, custom API, shared scripts, and permissions
Shared Scripts
Make scripts accessible from other scripts
Like creating Node Modules
NPM
Ability to use ‘npm install module’ to download NPM modules
Currently accessible from Custom API only

26. Scheduler, Custom API, Script Source

27. Diagnostics, Logging, Scale
API Calls, CPU Time, Data Out
Scale service based off of API Calls
Console logging from Scripts
Scale SQL DB / Server

28. Service Scale Free 500K API calls per subscription per month Standard
1.5M API calls per unit per month
Premium
15M API calls per unit per month
