  • Report Note

Here’s a breakdown of the pricing factors:

1. AWS S3 Pricing Components

a. Storage Costs

  • S3 Standard: $0.023 per GB for the first 50 TB/month.
  • S3 Infrequent Access (IA): $0.0125 per GB.
  • S3 Glacier (for archival): $0.004 per GB.

b. Request Costs

  • PUT, COPY, POST, LIST Requests: $0.005 per 1,000 requests.
  • GET, SELECT Requests: $0.0004 per 1,000 requests.

c. Data Transfer Costs

  • Within AWS (same region): Free.
  • To the internet:
    • First 1 GB per month is free.
    • After that, it's around $0.09 per GB for up to 10 TB/month.

2. Cost Estimation Example

Let’s say you upload 100 PDFs (total size 1GB) per month, and users download 10GB worth of files:

Cost Component Calculation Cost (USD)
Storage (S3 Standard) 1GB * $0.023 $0.023
Upload Requests 100 uploads (rounded to 1,000) * $0.005 $0.005
Download Requests 10,000 (assumed) * $0.0004 $0.004
Data Transfer (To Internet) 10GB * $0.09 $0.90
Total Estimated Cost ≈ $0.93/month

3. How to Reduce Costs?

  • Enable S3 Lifecycle Policies: Move old files to S3 IA or Glacier.
  • Use CloudFront CDN: Reduces data transfer costs by caching files closer to users.
  • Limit File Upload Size: Set restrictions via your backend to avoid unnecessary large file uploads.
