demoGetting Started

Application KeyNOT A SECURITY TOKEN/CONTROL

Hint that user is coming from your app (reduce chance of misuse)

Private until you publish the app

Master KeyAll powerful

Do NOT distribute with your application

Use from server-side logic you control

Security

Leverage Windows Azure Storage

Tables: schemaless entity storage; NoSQL

Blobs: 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) { });

Unstructured Data Storage

Leverage strengths of Windows Azure SQL DatabaseNew or Existing Database

Reporting, TSQL support, existing tools, etc.

Manage your way (portal, REST API, SSMS, etc.)

Partition applications by schemaApp1.Users

App2.Users

Dynamic Schema Support (on/off)

Structured Data Storage

DB

REST API

OData Interface

GET, POST, PATCH, DELETE

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

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

Authentication

Microsoft Account, Facebook, Twitter, and Google

OAuth

Does not use Windows Azure ACS

Authentication

Table level authorization for CRUD operationsEveryone: 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

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

Match against user.userId
