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.
