21- Use connection string for simplest setup
22- Use Entra ID for production with RBAC
23- Stream large files using chunks() to avoid memory issues
24- Create snapshots before major changes
25- Set quotas to prevent unexpected storage costs
26- Use ranges for partial file updates
27- Close async clients explicitly
