    Unit of authentication
    Unit of Geo-location
    Generated DNS based name
    Each database has standard SQL objects
    Unit of consistency
    Unit of multi-tenancy
    Contains Users, Tables, Views, Indices, etc.
    Most granular unit of billing

  • 16. Programming Model
    Small Data Sets
    Use a single database
    Same model as on premise SQL Server
    Large Data Sets and/or Massive Throughput
    Partition data across many databases
    Use parallel fan-out queries to fetch the data
    Application code must be partition aware in v1
    For v1 will publish best practices for scale out
    Post-v1 we are looking at building an abstraction to hide some of the complexities of partitioning
  • 17. Sharding Databases
    1 x 10GB database
    1 Instances
    10 x 1GB databases

  • 18. SQL Tooling & Development
    Demo
  • 19. Managing your account
  • 20. Viewing database information
  • 21.
  • 22. Sample screen – requires VS2010
  • 23.
  • 24. Compatibility Goals
    Support common application patterns
    Logical/policy based administration
    Patterns work from SQL Server to SQL Azure
    Multi-tenancy considerations
    Throttling and load balancing
    Limits on DB size, transaction duration, …
    V1: Address the needs of the majority of web and departmental application
  • 25. Sample of SQL Compatibility
    In Scope for v1
    Out of Scope for v1
    Tables, indexes and views
    Stored Procedures
    Triggers
    Constraints
    Table variables, session temp tables (#t)

    Distributed Transactions
    Distributed Query
    CLR
    Service Broker
    Spatial
    Physical server or catalog DDL and views
  • 26. 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)
  • 27. 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
  • 28. Deployment
    Support for basic deployment options
    SQL scripts work (but not attach database)
    Geo-location of Windows Azure compute and SQL Azure Databases
    Support for Application and multi-server management model
    Support for application packages
    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
  • 29. Security Model
    Uses regular SQL security model
    Authenticate logins, map to users and roles
    Authorize users and roles to SQL objects
    Limited to standard SQL Auth logins
    Username + password
    Future AD Federation, WLID, etc as alternate authentication protocols
    Security model is 100% compatible with on-premise SQL

    Reduced COGS with increased customerand business benefit:
    • Larger scale (e.g. larger customers ~20TB+ each)
    • 32. More self-managing (e.g. fault-tolerance)
    • 33. Better query performance for fan-out
    • 34. Faster provisioning of new customers
  • SQL AzureOpportunities and Futures
    Partitioned databases
    Geo-location and geo-redundancy
