Feature | Details |
---|---|
Database watcher for Azure SQL | Database watcher is a managed monitoring solution for database services in the Azure SQL family. Database watcher collects in-depth workload monitoring data to give you a detailed view of database performance, configuration, and health. Learn more about database watcher. |
Endpoint policies | Configure which Azure Storage accounts can be accessed from a SQL Managed Instance subnet. Grants an extra layer of protection against inadvertent or malicious data exfiltration. |
Fail over a link with T-SQL | You can now fail over a managed instance link by using Transact-SQL (T-SQL) commands. |
Free SQL Managed Instance | Try Azure SQL Managed Instance for free, for the first 12 months after you create your instance. |
Instance pools | Share resources between multiple instances in a pool within a single virtual machine. A convenient and cost-efficient way to migrate smaller SQL Server instances to the cloud, and the only way to deploy a 2-vCore managed instance. |
Link from SQL MI to SQL Server | Configure a link from Azure SQL Managed Instance to SQL Server 2022. |
Microsoft Entra nonunique name support | The CREATE USER Transact-SQL (T-SQL) syntax has been extended to include WITH OBJECT_ID to support creating Microsoft Entra logins and users in Azure SQL Managed Instance that have nonunique names. |
Native Windows principals | Use the new Windows authentication metadata mode to allow Windows authentication or Microsoft Entra authentication (using a Windows principal metadata) with Azure SQL Managed Instance. |
Next-gen General Purpose | An architectural upgrade of the General Purpose service tier that uses managed disks for greater resource flexibility, and improved performance while maintaining the same baseline cost as the General Purpose service tier. |
SDK-style SQL project | Use Microsoft.Build.Sql for SDK-style SQL projects in the SQL Database Projects extension in Azure Data Studio or Visual Studio Code. SDK-style SQL projects are especially advantageous for applications shipped through pipelines or built in cross-platform environments. |
Service Broker | Support for cross-instance message exchange using Service Broker between instances of Azure SQL Managed Instance, and between SQL Server and Azure SQL Managed Instance. |
Two-way DR with SQL Server 2022 | In the event of a disaster, you can fail your SQL Server 2022 workloads to Azure SQL Managed Instance using the link, and then, once the disaster is mitigated, you can fail back to SQL Server. |
Threat detection | Threat detection notifies you of security threats detected to your database. |
Zone redundancy for General Purpose | Deploy your General Purpose SQL Managed Instance to multiple availability zones to improve the availability of your instance in the event of a disaster. |

November 2022 feature wave
Changes and capabilities that were introduced in the November 2022 feature wave have been integrated to the majority of instances and are now available by default. Since taking separate action to enroll an instance is no longer necessary, options that mention the November 2022 feature wave have been removed from the Azure portal for instances that have enrolled in the feature wave. The last remaining instances are currently in the enrollment process.
All new instances on production subscriptions are enrolled in the feature wave by default if they are created in eligible subnets. The following subnet types are eligible:
- Newly created subnet (default)
- Existing subnets that are empty
- Existing subnets that already have the feature wave enabled, and contain only instances with the feature wave enabled
- Existing subnets that don't have the feature wave enabled, and contain only instances without the feature wave
The benefits in the feature wave include:
- Fast instance provisioning - It takes less time to deploy an instance.
- Improved network security - Internal service traffic is now isolated and secured by Microsoft.
- Enhanced virtual cluster - The functionality of the underlying virtual cluster is enhanced.
The features available in the wave are:
- Instance stop/start: You can start and stop your instance at your discretion to save on billing costs for vCores and SQL Server licensing.
- Zone redundancy for Business Critical tier: You can deploy your Business Critical tier managed instance across multiple availability zones to improve the availability of your service.
- Managed DTC: Run distributed transactions in mixed environments.
