Dr Keith Burns Data Architect Microsoft UK SQL Azure Highly available, scalable, multi-tenant database services in the cloud.

3 Session Objectives and Takeaways Session Objective(s): Get up to speed on SQL Azure Learn about the new features in SQL Azure Demonstration some working features in action Determine whether SQL Azure is ready for your application

4 The Windows Azure Platform

5 Extending SQL Server to the Cloud Database Data Sync Reporting Business Intelligence Symmetric Programming Model and tools  At PDC – core RDBMS capabilities with SQL Azure Database  Future Offerings  Additional data platform capabilities: Reporting, BI  New services: Data and Web Services

6 SQL Azure Hosted RDBMS Managed RDBMS – SQL query processor – Familiar relational model – Transactions – Ecosystem of familiar development and management tools – Low-friction provisioning – High scale – Multi-tenant – Self-management – Automatic HA and DR SQL Azure delivers the value of hosted relational database with the differentiated benefits of a managed database as a utility

13 Connection Model Use existing client libraries ADO.NET, ODBC, PHP Client libraries pre-installed in Azure roles Support for ASP.NET controls Clients connect directly to a database Cannot hop across DBs (no USE)

14 Logical vs. Physical Administration SQL Azure focus on logical administration Schema creation and management Query optimization Security management (Logins, Users, Roles) Service handles physical management Automatically replicated with HA “out of box” Transparent failover in case of failure Load balancing of data to ensure SLA DBA role places more focus on logical management

15 Deployment Support for basic deployment options SQL scripts work (but not attach database) Co-location of Windows Azure compute and SQL Azure Databases Support for Data Tier Applications DACPAC is unit of deployment Cloud or on-premise is a deployment time choice Visibility of data across on-premise and the cloud Support existing and new forms of deployment

16 Security Model Uses regular SQL security model Authenticate logins, map to users and roles Authorize users and roles to SQL objects Support for standard SQL Auth logins Username + password Future AD Federation, WLID, etc as alternate authentication protocols Security model is 100% compatible with on-premise SQL
