Professional Azure SQL Managed Database Administration - Third Edition

By: Ahmad Osama, Shashikant Shakya

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.

SQL Database serverless

SQL Database serverless automatically scales compute based on workload demand and bills for the amount of compute used per second. Serverless databases can also be configured to automatically pause during inactive periods when only storage is billed and automatically resume when database activity returns.

Serverless is available for single database deployments in the General Purpose tier of the vCore purchasing model at the time of writing this book.

Serverless use cases

Auto-scaling and auto-pausing and resuming in serverless often provide an optimal balance between performance and compute cost trade-offs for both production or development databases.

Serverless databases are well suited to the following scenarios:

  • Databases with intermittent, unpredictable usage patterns interspersed with periods of inactivity and lower average compute utilization over time.
  • New databases without usage history or SQL Server migrations where compute...
