DEMO TIME!!!

Shhh . . . It’s a Secret

Application KeyNOT A SECURITY TOKEN/CONTROLHint that user is coming from your app (reduce chance of misuse)

Private until you publish the app

Master KeyAll powerfulDo NOT distribute with your applicationUse from server-side logic you control

Unstructured Data Storage

Leverage Windows Azure Storage or Service BusTables: schemaless entity storage; NoSQLBlobs: storage for any binary object (files . . . whatever you want)Queues: simple messaging (push/pop)

Access via Windows Azure module for node.jsvar azure = require('azure');var tableService = azure.createTableService(‘<storage account>',‘<storage key>', 'table.core.windows.net');tableService.insertEntity(‘<table>’, entity, function(error) { });

Structured Data Storage

Leverage strengths of Windows Azure SQL DatabaseNew or Existing DatabaseReporting, TSQL support, existing tools, etc.Manage your way (portal, REST API, SSMS, etc.)

Partition applications by schemamycoupons.Usersspeakers.Users

Dynamic Schema Support (on/off)

Default System Columns

Column Type Description

id string Any unique stringIf not provided, server will create a unique value (GUID)

__createdAt date Set when item is inserted

__updatedAt date Set anytime there is an update to the item.Updated via database trigger.

__version timestamp Unique value updated anytime there is a change to the itemRead-only value

16

• Columns starting with ‘__’ (two underscores) will be rejected.• System columns not returned by default. Set ‘__systemProperties’ on request or

‘systemProperties’ in server

• azure mobile table create --integerId [service_name] [table_name]

Data Access

REST APIOData InterfaceGET, POST, PATCH, DELETE

https://<service>.azure-mobile.net/tables/<table_name>/{<item_id>}

AuthorizationX-ZUM0-{APPLICATION | AUTH | MASTER}

Source Control

• Enable via a Git repository• Portal• azure mobile preview enable SourceControl <service>

• Automatically pushed to the mobile service

node.js – Add your own modules

• Enable source control

• Go to ./service folder• npm install [module-name]• git add .• git commit –m “added stuff”

• Use in server scripts

Custom API

• HTTP request - GET, POST, PUT, PATCH, DELETEhttps://<service_name>.azure-mobile.net/api/<api_name>

• Request / response object implemented by express.js

exports.post = function(request, response) { // Use "request.service" to access features of your mobile service, e.g.: // var tables = request.service.tables; // var push = request.service.push;

response.send(200, "Hello World");

};

Scheduled Jobs

• Scheduled or on-demand• Scenarios• Archive / Backup data (i.e. SQL Database)• Purge stale records (i.e. Push Notification

channels)• Query external systems and store locally• Whatever you can think of

Push Notifications

Obtain Windows, Apple, or GCM push notification credentialsWindows: WNS client secret and package SID from Windows dev portal.Apple: Get a cert and create a profile from iOS Provisioning PortalGoogle: Get API key from Google API console

Enter appropriate notification credentials into the WAMS portal.

Ability to send Tile, Toast, Badge, and Raw notifications (Windows)

push.wns.* / push.apns.send (token, {alert, sound})Node.js module to create push notificationsHandles authentication against WNS, GCM, or APNS

Notification Hubs

May be ideal for working with multiple mobile clients.

Large number of clients & notifications.

DEMO TIME!!!

Authentication

Microsoft Account, Facebook, Twitter, and Google

Server-side / web-basedOAuthDoes not use Windows Azure ACS

Authentication

Microsoft Account – Use the Live SDKTight integration with Windows Live services

Client side authentication

Facebook Android SDK info at http://blogs.msdn.com/b/carlosfigueira/archive/2014/01/08/using-the-facebook-android-sdk-for-logging-in-to-azure-mobile-services.aspx

Authorization

Table & API authorizationEveryone: any request by anyone is accepted.Anyone with Application Key: app key distributed w/ the app (default)Authenticated Users: users that have been authenticatedScripts and Admins: registered scripts or requests via the master key

Your application can add whatever other authorization is needed.

Authorization

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