  39. 39. SQL Azure - Considerations<br />Doesn’t provide scalability out of the box and there is a hard limit of 50 GB per database instance. Application need to handle the partition logic <br />Since application has to build custom partition logic might incur sizable efforts to build such functionality<br />
  40. 40. SQL Azure Improvements <br />MARS (Multiple Active Results Sets), which simplifies the application design process <br />ALTER rename process for symmetry in renaming databases <br />Application and Multi-server management for Data-tier Applications which further streamlines application design and enables deployments of database applications directly from SQL Server 2008 R2 and Visual Studio 2010 to SQL Azure for database deployment flexibility <br />SQL Azure implements Open Data Protocol <br />

  42. 42. Summary<br />Key Takeaways<br />Microsoft will have a strong position in Cloud business software<br />SQL Azure is different than SQL Server and hosted SQL Server<br />SQL Azure will open up new scenarios and opportunities<br />Think about services / scenarios that have no “on-premises” equivalent<br />
