Change instance size (scale up), instance count (scale out), and autoscaling AppService
It would be great to have option to change instance size (scale up) and/or instance count (scale out). Additionally, it would be great to configure autoscaling. This will help with responding to alerts (such as high CPU).
This is definitely in the backlog. Let us know how important it is to you by voting it up!
