1. Situation 1
1.1. Total Storage (Hot): 522GB
1.2. Total PUT objects per month: 90.000 image files
1.3. Total GET objects per month: 90.000 image files
2. Situation 2
1.1. Total Storage (Hot): 13TB
1.2. Total PUT objects per month: 0 image files
1.3. Total GET objects per month: 100 image files
You must to calculate pricing monthly for both situations.

I’ll search for the current pricing information for AWS S3 and Azure Blob Storage to make an accurate comparison for both situations.Now I’ll calculate the pricing for both situations using the information gathered.## AWS S3 vs Azure Blob Storage – Cost Comparison

I’ve calculated the monthly pricing for both situations. Here’s the complete breakdown:

Situation 1: 522GB Storage + 90K PUT + 90K GET

AWS S3 (Standard – Hot Tier)

  • Storage: 522 GB × $0.023/GB = $12.01
  • PUT Requests: 90,000 × $0.005/1,000 = $0.45
  • GET Requests: 90,000 × $0.0004/1,000 = $0.04
  • TOTAL: $12.49/month

Azure Blob Storage (Hot Tier)

  • Storage: 522 GB × $0.018/GB = $9.40
  • Write Operations: 90,000 × $0.055/10,000 = $0.49
  • Read Operations: 90,000 × $0.0044/10,000 = $0.04
  • TOTAL: $9.93/month

Winner: Azure saves $2.56/month (20.5% cheaper)

Situation 2: 13TB Storage + 0 PUT + 100 GET

AWS S3 (Standard – Hot Tier)

  • Storage: 13,312 GB × $0.023/GB = $306.18
  • PUT Requests: 0 × $0.005/1,000 = $0.00
  • GET Requests: 100 × $0.0004/1,000 = $0.04
  • TOTAL: $306.18/month

Azure Blob Storage (Hot Tier)

  • Storage: 13,312 GB × $0.018/GB = $239.62
  • Write Operations: 0 × $0.055/10,000 = $0.00
  • Read Operations: 100 × $0.0044/10,000 = $0.04
  • TOTAL: $239.62/month

Winner: Azure saves $66.56/month (21.7% cheaper)

Key Takeaways

✅ Azure Blob Storage is more cost-effective in both situations

  • Azure has 22% lower storage costs ($0.018 vs $0.023 per GB)
  • Storage costs dominate the total bill in both scenarios
  • Request costs are minimal compared to storage costs

📊 Cost Breakdown by Component:

  • In Situation 1: Storage = 96% of costs, Requests = 4%
  • In Situation 2: Storage = 99.9% of costs, Requests = 0.01%

💡 Recommendations:

  • For storage-heavy workloads (like Situation 2), Azure provides significant savings
  • For high-transaction workloads, the gap narrows but Azure still wins
  • Consider Azure’s Cool or Cold tiers for even greater savings if access patterns allow
