10. Multimedia Storage (Actual vs Recomendado)

Tipo	Actual	Recomendado	Costo Estimado
Video	❓ Desconocido	S3 + CloudFront	$0.023/GB storage + $0.085/GB transfer
Imágenes	❓ Desconocido	S3 + CloudFront	$0.023/GB storage + $0.085/GB transfer
PDF	❓ Desconocido	S3	$0.023/GB storage
Audio	❌ N/A	S3 + CloudFront	$0.023/GB storage + $0.085/GB transfer

Costo mensual estimado (1,000 usuarios activos):

Videos (100 GB): $2.30 storage + $50 transfer = $52.30/mes
Imágenes (20 GB): $0.46 storage + $10 transfer = $10.46/mes
PDFs (5 GB): $0.12 storage = $0.12/mes
TOTAL: ~$63/mes (bajo, escalable)
