How do you monitor access and usage of storage?

Short answer: Use Azure Monitor, Metrics, and Diagnostic Logs. Track requests, bandwidth, errors, latency. Can integrate with Log Analytics or Application Insights.

Real-world example (ShopNest)

Product images upload to Azure Blob Storage; the DB only stores the blob URL.

2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
