2. Session Objectives and Takeaways
Get up to speed on SQL Azure
Learn about the architecture and cloud specific features of SQL Azure
Demonstration of some core features in action
Takeaways:
SQL Azure lets you innovate faster because it’s a managed service that lets you scale on demand
SQL Azure is uniquely positioned as an ideal data platform for Windows Azure applications

3. Notes (hidden)
This version of the deck was built for the Windows Azure Platform Training Workshop hosted Dec-2010 in Redmond WA by the DPE Platform Evangelism Team
The content is up to date as of SQL Azure Service Update 5 which shipped 22-Oct-2010

9. Service Provisioning Model
Account
Each account has zero or more logical servers
Provisioned via a common portal
Establishes a billing instrument
Each logical server has one or more databases
Contains metadata about database & usage
Unit of authentication, geo-location, billing, reporting
Generated DNS-based name
Each database has standard SQL objects
Users, Tables, Views, Indices, etc
Unit of consistency
Server
Database

10. Working With SQL Azure

11. Connection Model SQL Azure exposes native SQL Server TDS protocol
Use existing client libraries
ADO.NET, ODBC, PHP
Client libraries pre-installed in Windows Azure roles
Support for ASP.NET controls
Applications connect directly to a database
Cannot hop across DBs (no USE)

12. Connecting to SQL Azure
SQL Azure connection strings follow normal SQL syntax
Applications connect directly to a database
“Initial Catalog = <db>” in connection string
No support for context switching (no USE <db>)
Encryption security
Set Encrypt = True, only SSL connections are supported
TrustServerCertificate = False, avoid Man-In-The-Middle-Attack!
Format of username for authentication:
ADO.Net: Data Source=server.database.windows.net; User
Setup your firewall rules first!

13. 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 provides 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

14. Support existing and new forms of deployment
Deploy via T-SQL scripts
Support for SQL Server Data-Tier Applications (DAC) feature
DACPAC is unit of deployment
Cloud or on-premise is a deployment time choice
Create Logical Server in same region as Windows Azure Affinity Group for code-near architecture
Support existing and new forms of deployment

15. Security model is compatible with on-premise SQL
Uses regular SQL security model
Authenticate logins, map to users and roles
Authorize users and roles to SQL objects
Support for standard SQL Auth logins
Username + password
Security model is compatible with on-premise SQL

17. SQL Azure Compatibility
Currently Supported
Not Currently Supported
Tables, indexes and views
Stored Procedures
Triggers
Constraints
Table variables, session temp tables (#t)
Spatial types, HierarchyId
Data Types
XML, Sparse Columns, Filestream
Partitions
Full-text indexes
SQL-CLR
Tables require clustered indexes

18. Database Editions Two SQL Azure Database SKUs: Web & Business
Web Edition: 1 $9.99/month | 5 $49.95/month
Business Edition: Up to 50 $99.99/10 GB/month 10 $99.99 | 20 $ | 30 $ | 40 $ | 50 $499.95
You specify Web or Business Edition
Web: EDITION = web
Business: EDITION = business
You specify MAXSIZE
Web: MAXSIZE = 1GB | 5GB
Business: MAXSIZE = 10GB | 20GB | 30GB | 40GB | 50GB
This is the maximum size we will not let you grow beyond
You will only be charged for the actual peak size in any one day rounded up
For example, a 3.4 GB Web Edition will be charged 5GB rate.
CREATE DATABASE foo1 (EDITION='business', MAXSIZE=50GB);
CREATE DATABASE foo2 (EDITION='business', MAXSIZE=30GB);
ALTER DATABASE foo2 MODIFY (EDITION='web', MAXSIZE=5GB);
Business Edition
Up to 50 GB
10 GB increments
Web Edition
1 GB or 5 GB
