Introduktion till Azure SQL Database Robert Folkesson Active Solution

WHY?

SQL Database Service A relational database-as-a-service, fully managed by Microsoft. 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.
