What is Azure SQL Database?
A relational database-as-a-service, fully managed by Microsoft.
Delivers predictable performance, elastic scale, business continuity and programmatic functionality.
For cloud-designed apps when near-zero administration and enterprise-grade capabilities are key.
Perfect for cloud architects and developers looking for programmatic DBA-like functionality.

A Server Is Not A Machine
How is it different from VMs?
Best for…
SQL Server in a VM Azure SQL Database
Features
Resources
• Missing platform components
• Non supported T-SQL DDL constructs
• Non supported T-SQL DML commands
• Other gremlins
Unlikely that anything but the most trivial on-premises DB will be migrated without at least some changes
http://msdn.microsoft.com/en-us/library/windowsazure/ff394102.aspx
Windows Azure SQL Database != SQL Server
Tables without a clustered index and/or primary key
XML Schema on XML columns, XML indexing
User defined CLR types
FILESTREAM type
Etc. …
http://msdn.microsoft.com/en-us/library/windowsazure/ee336281.aspx
Non-supported DDL Easy to identify
BULK INSERT
OPENROWSET, OPENQUERY, OPENXML
Several of the Database Console Commands (DBCC)
EXECUTE AS LOGIN
Etc. …
http://msdn.microsoft.com/en-us/library/windowsazure/ee336253.aspx
Non-supported DML Harder to identify
Limitations on certain user names (sa, admin, root etc…)
USE {database} is not supported for DB context switching on a
single connection
Must specify the database name in the connection string
ALTER INDEX REORGANIZE (Must REBUILD)
Etc. …
Other gremlins

Introducing new service tiers
Elastic scale & performance: Six performance levels across three tiers for scale up and down based on throughput needs. Better resource isolation Improved billing experience.
Business continuity: A spectrum of business continuity features from light-weight to mission-critical across the tiers. Customers can dial up the control over data recovery and failover.
Familiar & Self-managed: Unprecedented efficiencies as your applications scale with a near-zero maintenance service and a variety of familiar management tools & programmatic APIs.
Azure SQL Database New Service Tiers
App Scalability & Performance
Business Continuity
Developer Efficiency
Massive scale & performance
Business continuity & data protection
Familiar management tools & APIs, Self-managed
*SLAs will take effect at time of GA, Azure previews are subject to different service terms, as set forth in preview supplemental terms.
**Not all restore & disaster recovery features are available today, visit the disaster recovery documentation page to learn more.
Dashboard views of metrics
Quickly understand DB resource usage via percent of resources
consumed for each resource type over time and database size Monitor
Available in the management
portal & via APIs
In contrast to a VM, no system-
related overhead—focused on
just the resources used to run
your database workload
In-depth views (DMVs) are also
available for deeper
understanding and trouble-
shooting (for example, at the
query level)
Self-service restore
Auto backups, transactional logs every
5 min
Backups in Azure Storage and geo-
replicated
Creates a side-by-side database copy,
non-disruptive
REST API, PowerShell or Azure Portal
Backups retention policy:
• Basic, last known state up to 24 hrs
• Standard, up to 7 days
• Premium, up to 35 days
Programmatic “oops recovery” of data deletion or alteration
Geo- replicated
Restore from backup

RTO<1h, RPO<5m, you choose when to failover
Mission-critical business continuity on your terms, via programmatic APIs
Up to 4secondaries
