Azure App Service Plan | Scale up/ Scale out grayed

We need to scale up the app service plan for already deployed function app. But Scale up option is disabled in Azure portal ? Please any one have experience on this

Solution 1:

It looks like you have an Y1 App Service Plan which is a so-called Consumption plan:

Scale automatically and only pay for compute resources when your functions are running. On the Consumption plan, instances of the Functions host are dynamically added and removed based on the number of incoming events.

So you can't scale your Consumption plan because it scales automatically. You might consider switching to a dedicated plan (See: Dedicated hosting plans for Azure Functions)
