Autoscaling allows a user to set a policy based on predefined criteria that manage the number of available instances in both peak and off-peak hours. Autoscaling with elastic load balancing works by attaching a load balancer and an autoscaling group so it can route all requests to all instances equally.
How do I create AutoScale rules in azure?
To create autoscale rules, you need an existing virtual machine scale set. You can create a scale set with the Azure portal, Azure PowerShell, or Azure CLI. If your application demand increases, the load on the VM instances in your scale set increases.
How do AutoScale rules work in scale sets?
When an autoscale rule triggers, your scale set can automatically scale in one of the following ways: A fixed number of VM instances to create. Useful in scale sets with a smaller number of VMs. A percentage-based increase of VM instances.
