  2. Problem Statement Windows Azure (Cloud hosting platform) is new and bugs need to be found Playing the role of 3rd party developer to design and implement a web system which should then be migrated to the Microsoft Azure Cloud. Must use: • Silverlight • Azure, Microsoft SQL, RIA Services

  3. Requirements • Create an application that tests Azure’s capabilities and general issues • Cloud Hosting Power • Security/Personalized Information • Integration with application • Use Required Systems • Windows Azure • Silverlight • RIA • Document cloud migration issues • At the same time choose a challenging project that we can enjoy working on

  4. Project Proposal • A Personalized Reader • Fetches articles or blog posts that matches your search criteria • This differs from other search engines… • Our system allows for passive users • Searches specific stories on specific domains • Proactive search apposed to reactive (on demand) • User’s history/results are saved

  5. Concept Diagram

  6. Development Environments • Visual Studio 2008 • .NET framework • Silverlight • RIA • Azure SQL • Subversion • Virtual Machines with remote access

  7. Customer Functional Requirements • Must be hosted on the Azure Platform • Must use Silverlight for the user view • Must use RIA Services to perform the middle tier operations • Must be a user centric applications which includes user profiles • Ability to iteratively update application once already installed on Azure

  8. Customer Non-Functional Requirements • User security (profile and user data is private) • Project must scale with user traffic appropriately (throttling) • Background operation of fetching materials is efficient (third party libraries and throttling)

  9. Architectural Sequence Diagram

  10. Sequence Diagrams

  11. Demo Show Demo of Cloud Reader Application • Login Functionality            • Atomic CRUD Operations

  12. Design Constraints • How to add different search engines?       (Modularization) • How do different search engines return results?      (Hierarchical interfaces, Results -> ImageResult, TextResult) • How can we throttle the processing usage?      (Thresholds for computed time to complete queues)  • How can we limit exceeding our allocated storage resources?     (User quotas)

  13. Technical Approaches (Overview)

  14. Technical Approaches (Entity Framework)

  15. Technical Approaches(Server Side Framework)

  16. Testing Description • Automated unit tests      (Entity CRUD Operations, Search engine queries) • Visual inspection      (Interface interaction) • Stress/Performance testing      (High/Medium/Low load testing, throttling inspection)

  17. Measurable Milestones • Twitter working on one account • More than one data source working • Migrate application to Microsoft Azure Cloud • Full Scale Testing / Real Time Interaction • Ability to demonstrate throttling abilities

  18. Risks •  Learning Curve (New technology, confusing/conflicted documentation) • Server side processing • Interface Usability (Silverlight issues) • Third Party API limitations (Rate limiting on Twitter, Digg, Reddit, ect.) • Migrating to Azure Cloud (Compatibility issues) • Client does not want the application; instead, they want to know the difficulties we faced

  19. Project Resource Costs • Project Hosting (break down on following slide) • Microsoft has provided student software site licenses •  Visual Studio IDE •  Microsoft SQL Server •  Windows Server

  20. Hosting Costs

  21. Conclusion A lot of progress has been made and we about on par with our original aggressive goals.

  22. Conclusion • Positive Feedback from Microsoft • Positive Feedback from Adviser • Working Demo produced to perform atomic CRUD operations on entities and user account authentication • Progress is starting on the background server operations

  23. Plan for Next Semester • Labels • "Creating a Label", "Saving a Label", and "Editing a Label" • 4/30/2010 • Rules • "Scheduling Rules", "Rule Based Searching", "view Results", "Remove Results", and "Remove Label" • 5/31/2010 • Validation and Throttling • 6/30/2010 • Rule Support • 7/31/2010 • Search Digg and Twitter • 9/30/2010 • Stress Test • 10/31/2010 • Final Documentation
