  • 3. Microsoft SQL AzureInformation Platform as a Service Managed Service Scale on Demand Innovate Faster Platform capabilities delivered as a service (Database, Data Database as a utility with Innovate with new data Sync, Reporting…) pay as you grow scaling application patterns Reduced complexity, greater Rely on Business-ready Build cloud-based data flexibility SLAs solutions on a familiar relational model Easy provisioning and Enable multi-tenant deployment solutions Build on existing developer skills and familiar Transact- Auto High availability and Manage multiple servers SQL syntax fault tolerant
  • 4. Subscription Used to map service usage to the billing instrument Users may have many subscriptionsLogical Server Akin to SQL Server Instance Unit of Geo-Location & Billing 1:1 Subscription & serverUser Database Restricted T-SQL surface area Additional catalog views provided e.g. sys.billing, sys.firewall_rules, etc
  • 5. A relational DB in the cloud SQL Azure Database Data Hub Others (Future) .NET Services SQL Services Applications Relational database as a service Live Services Windows Azure Highly available, automatically maintained Extension of the SQL Server Data Platform Applications Windows Windows Windows Others Server Vista/XP Mobile
  • 6. Single Logical Multiple Physical Database Replicas Repli ca 1 Repli D ca 2 B Repli ca 3
  • 7. Reference Data Sync Data Symmetric Programming Model Data Hub Aggregation• Initial services – core RDBMS capabilities with SQL Azure Database, Data Sync• Future Offerings • Additional data platform capabilities: Reporting, BI • New services: Reference Data
  • 8. Clear Feedback: “I want a database in the Cloud”Familiar SQL Server relational modelUses existing APIs & toolsBuilt for the Cloud with availability and scaleAccessible to all from PHP, Ruby, and JavaFocus on combining the best features of SQL Server running at scale with low friction

  • 14. Subscription Coordinated across all Azure services Executed in parallel w/retriesServer May occur between data centers Point where Geo-location is establishedDatabase Always occurs within a single data center Cross node operations executed during this process e.g. add new db to sys.databases on the master

  • 17. AccountServerDatabase
  • 18. Build a custom OData Service?Configure and Deploy your OData Service?Reach your audience?Share only what you want?Plan for the future?
  • 19. OData is the easiest way to share dataDo it wrong and it will cost youMobile and JavaScript clients are importantSharing too much can hurt your careerThings change.
  • 20. “Open Data”
  • 21. The “Open DataProtocol”
  • 22. 1. Based on HTTP & ATOM2. Open Specification Promise HTTP/ATOM + QUERY + JSON + METADATA
  • 23.  HTTP Reach (devices and platforms) Metadata Formats (ATOM & JSON) Semantics(GET/PUT/POST/ DELETE) Uri Conventions & Query Language
  • 24. HTTPSuitable for devicesSimplePowerfulEco-system Platforms: Javascript, PHP, Java, .NET, Silverlight, Ruby, i OS etc Producers: SharePoint, DataMarket, CRM, StackOverflow, Netflix etc.
  • 25. For development you need: Windows Azure SDK and Windows Azure Tools for VS Azure account with at least: One Storage Account One Hosted Service Registered Certificate SQL Azure Database
  • 26. Options Use SSIS Script Database and run script in new database Code in your app to initialize database(Coming Soon)http://www.sqlazurelabs.com/ImportExport.aspx (EXPORT) DacImportExportCli.exe -s serverName -d databaseName -f C:filePathexportFileName.bacpac -x -e (IMPORT) DacImportExportCli.exe -s serverName.database.windows.net -d databaseName -f C:filePathexportFileName.bacpac -i
  • 27. .getJSON(..) <script> {“x”:1} callback({“x”:1})
  • 28. Authentication & Authorization Authenticates and sets: HttpContext.Current.User
  • 29. AuthN Windows Auth – simple for in the enterprise services Basic Auth – maximum reach Forms Auth – purely for integration OAuth – most flexible – but needs custom code OAuth HttpModule Custom client code to acquire credentials
  • 30. authentica tes Gives consent someone@facebook.com someone@facebook .comAuthenticates and sets: HttpContext.Current.User
  • 31. Try to Authenticate someone@mycorp.c om someone@mycorp.comAuthenticates and sets: HttpContext.Current.User
  • 32. need to access x@y.com‟s data token: x@y.com token: x@y.com canread canreadAuthenticates and sets: HttpContext.Current.User
  • 33. WithDataServiceContext.IgnoreMissingProperties: You can safely Add a new optional property Remove a property – Read Only Add unrelated new types But lots of things can go wrong. Add a required property or navigation Remove a property – Read/Write Rename a property (fail). Remove a type / feedRealistic Solution V1/service.svc/ V2/service.svc/
  • 34. You just learned how to: The easiest way to build a web-api The easiest way to host a web-api How to do it the right way: Configuration Security & Reach VersioningYou know how to create a REAL service…
