Simulate serverless keep-alive policies on the Azure Functions trace

Replay per-minute invocation counts to compare fixed keep-alive windows with a per-application histogram policy on cold-start rate and idle memory time.

The exercise happens on Self-directed (Azure Public Dataset). Canonical link: https://github.com/Azure/AzurePublicDataset/blob/master/AzureFunctionsDataset2019.md. Link check: link responded (5 Oct 2026). Opened from this app 0 times; opening is not counted as an attempt.

Supports: Runs on a laptop with a sample of applications. Prepares trace-driven evaluation and cold-start trade-off discussions.
