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
SQL Azure Database
Highly scaled out relational database as a service
Relational database service
Browser
• SQL Server technology foundation
SOAP/REST
HTTP/S
• Highly symmetrical
ADO.NET/REST - EDM
HTTP/S
• Highly scaled
• Highly secure

- AD Federation (LiveId /AppFabric AC)
Database “as a Service” – beyond hosting
Customer Value Props
 Self-provisioning and capacity on demand
 Symmetry w/ on-premises database platform
 Automatic high-availability and fault-tolerance
 Automated DB maintenance (infrastructure)
 Simple, flexible pricing – “pay as you grow”
SQL Azure Network Topology
Application
Applications use standard SQL client
libraries: ODBC, ADO.Net, …
TDS (tcp:1433)
Load Balancer
Load balancer forwards ‘sticky’
sessions to TDS protocol tier

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

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
Server
Contains metadata about the databases and usage
Unit of authentication
Unit of Geo-location
Generated DNS based name
Each database has standard SQL objects
Database
10
Unit of consistency
Unit of multi-tenancy
Contains Users, Tables, Views, Indices, etc.
Most granular unit of billing
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

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

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

Cursors
Index management and
rebuilding indexes
Local temporary tables
Reserved keywords
Stored procedures

Tables, joins, and table
variables
Transact-SQL language

Create/drop databases
Create/alter/drop tables
Create/alter/drop users
and logins

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
Migrating Database Schemas
to SQL Azure
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
Moving Data into SQL Azure
with SSIS
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
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
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
