GENERAL PURPOSE PROGRAMMING LANGUAGES
App Fabric
Compute
Management
Relational database
CDN
Storage
Data Sync
Marketplace

SQL Azure DatabaseThe first and only true relational database as a service
Elastic Scale
Self-managed
Developer Agility
Build cloud-based database solutions on consistent relational model
Leverage existing skills through existing ecosystem of developer and management tools
Explore new data application patterns
Database utility; pay as you grow
Business-ready SLAs
Enable multi-tenant solutions
World-wide presence
Easy provisioning and deployment
Auto high-availability and fault tolerance
Self-maintaining infrastructure; self-healing
No need for server or VM administration

Data tier AccessApplication Migration

Data Access APIs
Supported APIs
Connection String
ADO .NET
Encrypt=True and add @servername to User ID
ODBC
Encrypt=yes and add @servername to Uid

Data Access APIs cont.
Protocols
Authentication Mode

Connectivity
Robust Connection Management through Retry Logic
Great Read: Connection Management in SQL Azure http://bit.ly/kWHfIJ
Flaky network connectivity
Code-Far topology
Failover
HW Failures or Upgrades
Resource Management Operations
Throttling and Load Balancing
ALTER DATABASE (T-SQL)
Changes to Database Name or MAXSIZE/EDITION
ALTERDATABASE [TestDb] MODIFY (MAXSIZE=50GB, EDITION='business')
GO

Security Management
Manage Logins - Authentication - SQL Server (only)
CREATELOGIN [testlogin] WITHPASSWORD='password'
Common login names such as ‘sa’, ‘admin’, ‘administrator’, ‘root’, and ‘guest’ are not allowed,
Manage User
CREATEUSER testuser FROMLOGIN testlogin;
Manage Server Roles
Two new database role (only in master)
EXECsp_addrolemember'dbmanager','testuser';
Similar to [dbcreator]
EXECsp_addrolemember'loginmanager','testuser';
Similar to [securityadmin]
Views
sys.sql_logins. sys.databases, sys.database_principal

Firewall Management
Portal Access
Programmatic Access
System Views and Stored Procedures – http://bit.ly/mzhBjw
View: sys.firewall_rules
Stored Procedure: sp_set_firewall_rule
Stored Procedure: sp_delete_firewall_rule
API Implementation Example – http://bit.ly/mCKzqV

Collations
Default Collation
Set to SQL_LATIN1_GENERAL_CP1_CI_AS
Applies to…
Metadata, TempDb and Default for User Data
Object Names (tables, sprocsetc), String variables and Columns when no collation is specified.
Use column and/or expression level collation when needed
CREATETABLE [dbo].[ErrorLog](
[ErrorLogID] [int] IDENTITY(1,1)NOTNULL,
[ErrorTime] [datetime] NOTNULL,
[UserName] [nvarchar(4000)] COLLATETurkish_100_CI_AINOTNULL,
[ErrorNumber] [int] NOTNULL,
[ErrorMessage] [nvarchar](4000)COLLATEJapanese_CI_ASNOTNULL,
CONSTRAINT [PK_ErrorLog_ErrorLogID] PRIMARYKEYCLUSTERED ([ErrorLogID] ASC)
)
DECLARE@strnvarchar(128)COLLATEGreek_CS_AI

Feature Parity
Administration Surface
Physical Server Properties does not apply in SQL Azure
You have a master database but no access to server level constructs such as sp_configure, endpoints, DBCC commands, server level DMVs and System Views
Programmability Surface
Certain Features are partially available today
USE, XML processing, deprecated T-SQL etc.
List is available here; http://msdn.microsoft.com/en-us/library/ee336267.aspx
Some features are not available today
Full-text Search, Remote Data Access and Linked Servers, Distributed Transactions, Change Tracking, Service Broker etc.

Summary – Database MigrationOne-Off Migration Tools for SQL Server

SQL Server Management StudioGenerate Script Wizard
Scenario
Migration of schema and/or data with fine grain control.
Pros
Native support for SQL Azure Schema options: “Engine Type = SQL Azure”
Ensures correct options and settings are applied for the TSQL script generation.
Requires explicit action on unsupported objects.
Cons
Verbose – INSERT Statements instead of raw data
Data is scripted with a fixed 100 row batch size.
Edit “GO” statements between small batches
Round-trip Efficiency
Use “SET NOCOUNT ON”
Stops processing on first incompatibility

Data-tier Application (DAC) Packages
Scenarios
Self contained package for moving schema easily through the development lifecycle
What is a DAC Pack?
Single unit for authoring, deploying, and managing the data-tier objects
Development Lifecycle (VS 2010)
Editing DACs
Schema and DB Code Development,
Code Analyses, Deployment Policy Settings,
Schema Comparison and more…
Building DACs – the self contained database package
Management Lifecycle (SSMS 2008 R2)
Managing DACs
Registering existing database as DACs
Deploying and Upgrading databases using DACs,

SQL Server Management StudioImport and Export Wizard
Scenario
Simplified wizard for migrating schema and data through SSIS
Pros
Great performance out of the box
Allows ‘save as package’ for full control
