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

Build a custom OData Service?Configure and Deploy your OData Service?Reach your audience?Share only what you want?Plan for the future?

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.

“Open Data”

The “Open DataProtocol”

1. Based on HTTP & ATOM2. Open Specification Promise HTTP/ATOM + QUERY + JSON + METADATA

 HTTP Reach (devices and platforms) Metadata Formats (ATOM & JSON) Semantics(GET/PUT/POST/ DELETE) Uri Conventions & Query Language

HTTPSuitable for devicesSimplePowerfulEco-system Platforms: Javascript, PHP, Java, .NET, Silverlight, Ruby, i OS etc Producers: SharePoint, DataMarket, CRM, StackOverflow, Netflix etc.

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

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

.getJSON(..) <script> {“x”:1} callback({“x”:1})

Authentication & Authorization Authenticates and sets: HttpContext.Current.User

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

authentica tes Gives consent someone@facebook.com someone@facebook .comAuthenticates and sets: HttpContext.Current.User

Try to Authenticate someone@mycorp.c om someone@mycorp.comAuthenticates and sets: HttpContext.Current.User

need to access x@y.com‟s data token: x@y.com token: x@y.com canread canreadAuthenticates and sets: HttpContext.Current.User

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/

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…
