Currently, I'm working on web app scaling out configuration.
My goal is to create additional instances as soon as the CPU increases to 40% or more. I've done some configuration and it works.
Here is my configuration.

But the problem is that it responds to the metrics not immediately. Usually, it takes a few minutes before scaling and this is something that is not acceptable in my case.

Is it possible to make the scaling process respond to metrics changes faster?

    Hi, here is a best practices articles on this process: https://learn.microsoft.com/en-us/azure/azure-monitor/autoscale/autoscale-best-practices#choose-the-thresholds-carefully-for-all-metric-types

    There is also a preview feature for predictive autoscaling for Virtual Machine Scale Sets (not App Service) which might be of interest as an alternative option for you: https://learn.microsoft.com/en-us/azure/azure-monitor/autoscale/autoscale-predictive
