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.

Summary

In this chapter, you learned about the high availability and DR features of Azure SQL Database and SQL Managed Instance. High availability is built into Azure SQL Database and SQL Managed Instance and is managed by Microsoft, whereas DR can be achieved by configuring active geo-replication and failover groups as and when required.

You also learned about ADR, a new feature introduced with Azure SQL Database, SQL Managed Instance, and SQL Server 2019, which provides instant database recovery, transaction rollbacks, and aggressive log truncation.

Furthermore, you saw how zone-redundant configuration provides additional high availability by replicating the database in multiple Availability Zones within the same region.

In the next chapter, you will learn about how to monitor an Azure SQL Database and SQL Managed Instance using the Azure portal, dynamic management views, and extended events to help improve the performance of your application.
