Who am I?

Familiar SQL Server relational model
Uses existing APIs & tools
Friction free provisioning and reduced management
Built for the Cloud with availability and scale
Accessible to all from PHP, Ruby, and Java
What is SQL Azure

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
Special ConsiderationsDatabase Size

Support common application patterns
Logical/policy based administration
Patterns work from SQL Server to SQL Azure
Multi-tenancy considerations
Throttling and load balancing
Limits on DB size, transaction duration

Connect via ADO.NET, ODBC, etc.
OLE DB is NOT supported
May need to include <login>@<server>
Use familiar tools (sqlcmd, osql, SSMS, etc)
Current version of SSMS is not fully supported but it works
SSMS 2008 R2 CTP has connection capability

Since SQL Azure supports only a subset of features, some modifications need to be made
Migrating an existing schema
User Defined Data Types
Specifying Filegroups
Extended Properties
USE DATABASE
NOT FOR REPLICATION
Various Index options
Windows logins
Unsupported XML features
Indices need to be clustered
