3. Reporting Business Analytics Data Sync
 The Power of the SQL Data Platform in the cloud
 Leverages existing skills and rich tooling ecosystem
 Enables database applications with new, “cloud” capabilities

4. SQL Azure Database
Highly scaled out relational database as a service
Relational database service
Browser
• SQL Server technology foundation
• Highly symmetrical
SOAP/REST ADO.NET/REST - EDM
HTTP/S HTTP/S • Highly scaled
• Highly secure
App Code
(ASP.NET)
Database “as a Service” – beyond hosting
SQL Server Report Server
Windows Azure (on-premises)
Customer Value Props
Compute
 Self-provisioning and capacity on demand
T-SQL (TDS) T-SQL (TDS)
 Symmetry w/ on-premises database platform
SQL Azure  Automatic high-availability and fault-tolerance
Database MS
 Automated DB maintenance (infrastructure)
Datacenter
 Simple, flexible pricing – “pay as you grow”
- AD Federation (LiveId /AppFabric AC)

5. SQL Azure Network Topology
Applications use standard SQL client
Application libraries: ODBC, ADO.Net, …
TDS (tcp:1433)
Load balancer forwards ‘sticky’
Load Balancer sessions to TDS protocol tier
TDS (tcp: 1433)

Scalability and Availability: Fabric, Failover, Replication and Load balancing

6. Performance Considerations
The distance your application travels to perform data
access will affect performance

9. Service Provisioning Model
Each account has zero or more servers
Account Azure wide, provisioned in a common portal
Billing instrument
Each server has one or more databases
Contains metadata about the databases and usage
Unit of authentication
Server Unit of Geo-location
Generated DNS based name
Each database has standard SQL objects
Unit of consistency
Database Unit of multi-tenancy
Contains Users, Tables, Views, Indices, etc.
Most granular unit of billing

10. Setting Up SQL Azure Account
Request token for SQL Azure at
http://www.azure.com/
Tokens will generally be provisioned within a
couple days
Redeeming tokens
Setup administrative user
Specify geo-location

14. Connecting to SQL Azure
Connect via ADO.NET, ODBC, etc.
OLE DB is NOT supported
May need to include <login>@<server>
USE statement is NOT currently supported
Use familiar tools (sqlcmd, osql, SSMS, etc)
Current version of SSMS is not fully supported
but it works (demo to come)
Tools will evolve before PDC for increased
support

15. Connecting to SQL Azure

16. SQL Azure Security
Supports SQL Server Security
On-premise SQL Server security concepts still
apply
Server-level: sds_dbcreator, sds_securityadmin roles
Database-level: same as on-premise SQL Server
SSMS Object Explorer is NOT currently
supported
Administrative user is equivalent to sa

17. Managing Logins & Security
in SQL Azure
18

18. T-SQL Support (full or partial)
Constants Tables, joins, and table
Constraints variables
Cursors Transact-SQL language
Index management and elements such as
rebuilding indexes Create/drop databases
Create/alter/drop tables
Local temporary tables
Create/alter/drop users
Reserved keywords and logins
Stored procedures …
Statistics management User-defined functions
Transactions Views
Triggers
19

19. T-SQL Not Supported (v1)
Common Language SQL Server configuration
Runtime (CLR) options
Database file placement SQL Server Service Broker
Database mirroring System tables
Distributed queries Trace Flags
Distributed transactions
Filegroup management
Full Text Search
Global temporary tables
Spatial data and indexes
20

20. Creating Objects in SQL Azure
21

21. Migrating Databases
“Just change the connection string”
* once database is migrated
Generate script wizard from SSMS currently
creates unsupported DDL
SQL Server Management Studio 2008 R2 has
increased support for SQL Azure
Migrating Databases to SQL Azure HOL in the
Windows Azure Platform Training Kit
22

22. Migrating Database Schemas
to SQL Azure
23

23. Moving data
Scripted INSERT statements
SQL Server Integration Services
Available in Developer and Trial editions
Use ADO.NET endpoint
BCP (bulk copy) is supported
DataSync will enable Microsoft Sync Framework
24

24. Moving Data into SQL Azure
with SSIS
25

25. Special Considerations: Database
Size
Maximum single database size is currently 10GB
Database size calculation
Includes: primary replica data, objects and indexes
Does NOT include: logs, master database, system
tables, server catalogs or additional replicas
V1 does not support auto-partitioning or fan-out
queries
Must handle partitioning logic within the application
See scale out SQL Azure content within the Windows
Azure Platform Training Kit for additional guidance
26

26. Special Considerations: Throttling
MSDN
• Use traditional SQL Server best practices
• CTP cluster has throttling limits turned up to allow for building
logic into apps for handling this case
• Build in retry logic especially if you expect very high throughput
demands
• Consider scaling out for high throughput scenarios
27

27. Special Considerations: PHP
SQL Azure does NOT support Multiple Active
Result Sets (MARS)
Must use the SQL Server for PHP v1.1 or newer
with MARS connection option set to FALSE
