New features introduced to Microsoft’ Cloud data platform make it easier for customers to migrate away from on-premise deployments, according to David Robinson, SQL Azure senior program manager. In this regard, SQL Azure now features Multiple Active Results Sets, ALTER rename and Application and Multi-server management. The evolution of SQL Azure was announced at the end of the past week, and the new additions are now live for customers to leverage and test-drive.

“These news features include: MARS (Multiple Active Results Sets), which simplifies the application design process; ALTER rename process for symmetry in renaming databases; 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,” Robinson stated.

Earlier this month, Microsoft expanded the global availability of the Windows Azure platform, which also includes SQL Azure. Both the Cloud operating system and the data store are now available to customers in 41 countries and regions worldwide, up from 21 when Windows Azure was initially introduced. Streamlining migration from on-premise to the Cloud is a strong focus for Microsoft, and, with the new SQL Azure features, the company aims to simplify design and deployment tasks for customers opting for hosted Database Management Systems (DBMS).

“Many customers have looked to SQL Azure as an alternative to MySQL due to the fact that it provides a simple way to offer a highly available and publicly accessible data store. A primary issue customers have faced in the migration process from a database such as MySQL is the ability to support multiple active resultsets (MARS),” Robinson added.

In addition, the Data-tier Application allows customers to register and deploy Data-tier Applications on SQL Azure, by leveraging tools such as Visual Studio 2010 and SQL Server Management Studio 2008 R2 (for deployment), and SQL Server Management Studio 2008 R2 (for registration). Databases can now also be renamed in order to ensure symmetry with SQL Server, via the ALTER rename option.
