With Azure Arc, you can run Azure data services anywhere: on-premises, multi-cloud, and edge environments. Azure Arc enabled data services simplify data management with features such as automated provisioning, elastic scaling, and unified management from Azure. Today, we are happy to continue down this journey and announce the preview of Always On Availability Groups for Azure Arc enabled Managed Instance for improved high availability.
Business continuity is a key requirement for many applications. On top of the high availability capabilities of Kubernetes which provides built-in health monitoring, failure detection, and automated redeployment mechanisms to maintain service health, Azure SQL managed instances can now be deployed with additional replicas for increased reliability. With a single deployment command, you can easily deploy an Azure SQL managed instance with a system-managed Always On Availability Group backed by multiple replicas.
Azure Arc enabled SQL Managed Instance Always On Availability Groups offer the following capabilities:
Deploying a managed instance backed by multiple replicas is easy. The following command deploys the architecture diagram illustrated above in your Kubernetes cluster.
azdata arc sql mi create -n myinstance --replicas 3
