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

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)

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

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
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

11

Account

SQL Azure
Accessing databases

Change Connection String

App

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

in SQL Azure

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

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

Creating Objects in SQL Azure

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

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
