Overview of this book

Despite being the cloud version of SQL Server, Azure SQL Database and Azure SQL Managed Instance stands out in various aspects when it comes to management, maintenance, and administration. Updated with the latest Azure features, Professional Azure SQL Managed Database Administration continues to be a comprehensive guide for becoming proficient in data management. The book begins by introducing you to the Azure SQL managed databases (Azure SQL Database and Azure SQL Managed Instance), explaining their architecture, and how they differ from an on-premises SQL server. You will then learn how to perform common tasks, such as migrating, backing up, and restoring a SQL Server database to an Azure database. As you progress, you will study how you can save costs and manage and scale multiple SQL databases using elastic pools. You will also implement a disaster recovery solution using standard and active geo-replication. Finally, you will explore the monitoring and tuning of databases, the key features of databases, and the phenomenon of app modernization. By the end of this book, you will have mastered the key aspects of an Azure SQL database and Azure SQL managed instance, including migration, backup restorations, performance optimization, high availability, and disaster recovery.

6. Security

Security is a major concern for organizations when migrating to the cloud, making them hesitant to actually do so. The major security concerns with the cloud include ones about physical server security, data security at rest and in motion, and data infiltration. Microsoft provides strong security protection at the physical, logical, and data layers of Azure services. Microsoft datacenters are among the most secure datacenters in the world.

Azure SQL Database and SQL Managed Instance provide multiple layers of security to control access to databases using SQL Server or Active Directory (AD) authentication as well as firewall rules, which limit access to data through role-based permissions and row-level security.

SQL Database and SQL Managed Instance provide proactive security using Advanced Threat Protection, granular access control, and strong authentication. In addition to this, dynamic data masking and row-level security can be used to secure data.
