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.

Connecting to Azure SQL Managed Instance

Azure SQL Managed Instance is a set of services hosted on one or more isolated virtual machines inside a virtual network subnet.

When we provision an Azure SQL Managed Instance, a virtual cluster is created. A virtual cluster can have one or more SQL Managed Instances.

Applications connect to databases via an endpoint, <mi_name>.<dns_zone>.database. windows.net, and should be inside a virtual network, a peered virtual network, or an on-premises network connected via VPN or Azure ExpressRoute.

Unlike Azure SQL Database, Azure SQL Managed Instance supports Azure Virtual Network (VNet). An Azure VNet is a logical boundary or isolation that groups resources within a specified Azure region and enables secure communication between resources, the internet, and on-premises networks:
