Question 1

You are designing a serverless architecture using Azure Functions.

The function will be triggered by HTTP requests. The workload is highly variable, with long periods of inactivity followed by sudden, massive spikes in traffic.

The application has a strict requirement: the response time for the very first request after a period of inactivity must be under 500 milliseconds. Furthermore, the function needs to securely access resources inside an Azure Virtual Network.
