@Jitendra Kumar

Can you kindly clarify your ask little bit ? Are you talking about auto scaling for VMSS ? There is no auto scaling feature for a single VM.

Regards,

Shiva.

My ask is I need to set the autoscaling feature based on the request count/traffic request
Min count for VM=2

max count for VM=10

But I need the scale out and scale in policy based on traffic request
I know how to set up based on CPU utilization. looking to set based on metrics.

Do you want to scale up the Application Gateway/Load Balancer or your backend Application?

Please note that scaling out the Application Gateway/Load Balancer (PaaS resource) will improve the number of requests the PaaS resource can handle.

In this case, if your backend is not scaled up, this will not improve the overall performance.

May I ask what your backend is?

If you are using VM as a backend, you can only Scale Up and not Scale Out

Scaling up may not improve networking throughput.

However, if you are using VMSS, you will be able to scale out the number of instances.

Your exact requirement is listed here : https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/virtual-machine-scale-sets-autoscale-portal#create-a-rule-to-automatically-scale-out

Make sure you define a Rule using the required metric according to your case.

Cheers,

Kapil
