4. Profile: Windows Phone 7
• Connectivity
• Easy to develop for
• Familiar development
environment
• Growing marketplace
• Best Feature: Transparency

5. Profile: Windows Azure
• Cloud == Connectivity
• Easy to develop for
• Familiar development
environments
(.NET, Ruby, PHP, Java
, etc.)
• Scalability
• Best Feature – Levels
the Playing Field

6. Dimensions of Compatibility
Windows Phone 7 Windows Azure
• Connectivity • Cloud Connectivity
• Easy/Familiar • Easy/Familiar
Environment Environment
• Marketplace • Scalability
• Transparency • Levels the Field

7. Windows Azure: Behind the Scenes
Windows Server 2008 / R2
.NET Framework 3.5 SP1 & 4.0
Runs on Windows Server -> Runs on Windows Azure
Virtual Machine – image/instance replicated as needed
Automatic load balancing (web roles)
Fabric Controller
• Resource allocation
• Recovery

8. Windows Azure: Behind the Scenes
Web Role Worker Role
• IIS7 (Automatic Setup) • Executable – Windows
Service
• Requires at least 1 input
endpoint • Serve as a host
– Web server, database, etc.
• Ideal for web applications
• Generalized development
• ASP.NET
• Long running or intermittent
• Fast CGI + PHP
tasks

9. The Key to Any Good Relationship -
Communication
Windows Phone Windows Azure
• WCF • HTTP
• OData • ASP.NET
• JSON • WCF
• POX • WCF Data Services
(OData)
• Node.js
request response
direct

10. Data Storage Options
Windows Azure SQL Azure
• Automatic scalability • Turn key SQL database
• REST-based API • Tabular Data Stream (TDS)
• Tables, blobs, & queues • DataSync (CTP)
• Automatic geo-replication • SQL Azure Reporting
Services (CTP)

11. Windows Azure Service Bus
Robust messaging and routing services
Ability to connect services across networks
• Defeats NATs and firewalls
• Great for hybrid application scenarios!
Uses ACS for security
Examples at http://servicebus.codeplex.com

12. Do I Know You? – Identity Management
No need to build your own identity management
• Another component to maintain
Likely not a distinguishable part of your application
Deal with user management
• User support
• Password management (including resets)

13. Do I Know You? – Identity Management
Roll Your Own
ASP.NET Membership Providers
• Table Storage
• SQL Azure
Integrate with Facebook, Windows Live, etc. via Access
Control Services
• Leverage ACS to handle authentication
• Claims-based approach

14. Windows Phone and Access Control Services
DEMO

15. The First Date – Table Time
Phone provides limited storage
Windows Azure
Non-relational data storage
Massive scalability (100 TB per Storage Account)
WCF Data Services (OData)
Security
• HTTPS
• Account Name and Key
Accessibility
• Direct – Secure you key?
• Web service (proxy)
TABLE

16. Second Date – A Movie
Blobs provide mechanism for storage & retrieval of
unstructured data.
Private by default.
Public read for web/phone apps.
Web role -> Blob?
Extra stress on the role instance

17. A Better Option
Get a little closer with Shared Access Signatures
• Secure, limited access direct to Blob storage.
• Create/Get Blob Container
• Create SAS
• Return SAS to WP7
• WP7 will PUT data to Blob using the SAS
• WP7 will GET data from Blob storage

18. Second Date – A Movie: CDN Edition
Windows Azure CDN
• 24+ edge cache servers worldwide
• Better user experience
• HTTP/HTTPS
CDN CDN CDN CDN CDN CDN
