You host a file compression utility named ZipArchiver on an Azure App Service Web App. The web app currently runs on a Basic (B2) App Service plan. During daytime operations, CPU utilization frequently spikes to 85%, causing request queues to build up. You need to configure the Web App to automatically scale out when CPU utilization exceeds 80% for more than 10 minutes, and scale in when CPU utilization drops below 40%.
What should you do first?
- AConfigure an autoscale setting with a scale-out rule directly on the Basic (B2) plan.
- BScale out the App Service plan manually to three instances using the Azure CLI.
- Scale up the App Service plan to the Standard (S1) tier.Answer
- DEnable the Local Cache feature for the App Service Web App.
Answer
Scale up the App Service plan to the Standard (S1) tier.
Scaling up the App Service plan to the Standard (S1) tier is the correct first step because the Basic tier does not support metric-based autoscale settings. Standard and higher tiers are required to configure automatic scale-out and scale-in actions based on CPU utilization.
