Automatic instance repairs for Azure virtual machine scale sets now in preview
Published date: 05 March, 2020
Azure virtual machine scale sets now provide the capability to automatically repair unhealthy instances based on application health status. Configure the scale set instances to emit application health by using either the application health extension or Azure load balancer health probes. After you enable the automatic repairs policy, when an instance is found to be unhealthy, the scale set will automatically delete the unhealthy instance and create a new one to replace it.
To learn more about this feature and to enable it for your scale sets, read the documentation.
