🚀 Production Scenarios

1. High-Traffic Nginx Access Log Purging: Daily cron job purging uncompressed access logs older than 14 days to prevent root partition disk exhaustion.
2. Windows Server IIS Application Pool Retention: Scheduled task pruning recursive nested request logs in C:\inetpub\logs\LogFiles older than 30 days.
3. Database Dump Rotation: Purging database dumps older than 7 days exceeding 50 MB in size.
4. CI/CD Runner Workspace Pruning: Cleaning build workspaces on self-hosted runners to prevent No space left on device errors.
