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, we covered different ways of monitoring and tuning Azure SQL Databases and SQL Managed Instances. We learned how to use Azure SQL Database performance metrics and Query Performance Insight to monitor database metrics and queries from the Azure portal.

The chapter talked about using Azure SQL Analytics to monitor Azure SQL Database and SQL Managed Instance. Intelligent Insights, provided by Azure SQL Analytics, can be used to set up alerts on different metrics such as CPU, log I/O, blocks, and deadlocks for Azure SQL Database. Intelligent Insights can also be used to fine-tune long-running and CPU- or I/O-intensive queries to further optimize an Azure SQL database.

We also learned how to set up alerts on database metrics, and proactively acted as and when alerts were raised. We learned about important DMVs and how to set up extended events to monitor a SQL database or a managed instance.

Following this, we set up automatic tuning for an Azure SQL database...
