D1 is Shared Tier and does not offer autoscaling. You need to switch to Standard, Premium or Isolated.

Tier D1 is a basically shared app service plan, so we need to move standard or premium plan to enable auto scaling. As we need to provide low cost solution, then standard plan will be best for this approach

This answer may not be correct anymore? From microsoft pricing page: https://azure.microsoft.com/en-us/pricing/details/app-service/linux-previous/ The Standard service plan is still available for running less demanding production workloads. Pricing is based on the size and number of instances you run. For greater savings and higher performance, we strongly recommend using the latest App Service Premium plan. Even still Standard is cheaper but you get less ram/storage. But standard pricing tier is being removed in favor of Premium.

The D1 tier plan is a basic tier plan that does not offer autoscaling. For using autoscaling, you have to change D1 basic tier plan to Others(Standard, Premium, Isolated, Consumption). The Standard plan is cheapest plan which has auto scaling. So Answer is C.

Standard Tier is the correct answer.

D1 is basic tier and It does not support auto scaling feature. => we should upgrade to Standard tier

Standard tier is the correct one.

C is correct. Auto scaling is supported on both Premium and Standard, but Standard is lower cost

Enabling autoscaling (option A) can still be a valuable addition to further optimize the resource allocation based on the actual demand. By combining autoscaling with the upgraded Standard App Service tier, you can automatically scale the resources up or down based on CPU load, ensuring optimal performance during peak traffic while minimizing costs during periods of lower traffic. Therefore, the recommended course of action in this scenario would be to switch to the Standard App Service tier (option C) and then enable autoscaling (option A) to effectively address the page load time issue during peak traffic while considering cost optimization.

why not D Consumption plan? https://learn.microsoft.com/en-us/azure/azure-functions/consumption-plan The Consumption plan scales automatically, even during periods of high load. When running functions in a Consumption plan, you're charged for compute resources only when your functions are running. On a Consumption plan, a function execution times out after a configurable period of time.

the first step is to upgrade the App Service plan to the Standard or Premium tier, if it is not already on one of these tiers, and then enable autoscaling on the Web App

Auto scale is NOT supported in tiers: Free (F1), Shared (D1 - only Windows) and Basic (B1, B2 and B3).

B. Switch to Standard as D1 does not allow autoscale. Standard is the cheapest option that supports autoscale.

First at all, your choices are Standard or Premium. Reduce cost => Standard.

I agree that we need to enable auto-scaling to reduce the cost. But the question is "What you should do first?" hence switching to the standard app service makes more sense

C. Switch to the Standard App Service tier plan.
