2. Virgílio Esteves ID&T – Research Leader @HIS & Founder of NetPonto Coimbra C# / WPF / Silverlight / XNA / Azure

3. Challenges  Data Storage  Connectivity  Authentication  Schema  T-SQL Supportability  Replication & Log Shipping

4. Data Storage  SQL Server  No size limits  SQL Azure  Web Edition  1GB or 5GB  Business Edition  10GB » 50GB (10GB increments)

5. Connectivity  Tools  Connection management

6. Connectivity: Tools  SQL Server  Management Studio (SSMS)  SQLCMD  Profiler  SQL Azure  Management Studio (SSMS) [2008 R2+]  SQLCMD  Portal

7. SQL Azure Network Topology Internet Azure Forwards “sticky” sessions to TDS protocol tier

8. Connectivity: Connection Management  SQL Server  No “default” connection termination  SQL Azure  Connection termination at server discretion  “Coded” reason codes

9. Connection Termination: Causes  Lock consumption  Uncommitted transactions  Transactions blocking system calls  Log file size  TempDB usage and size  Excessive memory usage  Maximum database size reached

10. Connection Termination: Causes  Idle connections  Long running transactions  Denial of Service attacks  Network problems  Failover problems  Load balancer discretion

11. “Coded” Reason Codes

12. Authentication  SQL Server  SQL Authentication  Windows Authentication  SQL Azure  SQL Authentication

13. Schema  SQL Server  No limitations  SQL Azure  Doesn’t support heaps  All tables must have a clustered index

14. T-SQL Supportability  SQL Server  No limitations  SQL Azure  Some are fully supported  Some are partially supported  Some are fully unsupported

15. T-SQL: Fully or Partially Supported  Constants  Constraints  Cursors  Index management and rebuilding  Local temporary tables  Reserved keywords  Spatial data and indexes  Stored procedures  Triggers

16. T-SQL: Fully or Partially Supported  User-defined functions  Statistics management  Transactions  Tables, joins and table variables  Create/Drop databases  Create/Alter/Drop tables  Create/Alter/Drop users and logins  Views

17. T-SQL: Unsupported  Common Language Runtime (CLR)  Database file placement  Database mirroring  Distributed queries  Distributed transactions  Filegroup management

18. T-SQL: Unsupported  Global temporary tables  SQL Server configuration options  SQL Server Service Broker  System tables  Trace flags

19. Replication & Log Shipping  SQL Server  Fully supported  SQL Azure  Not supported

20. Yes… But some things come to the rescue
