Question

What are the costs associated with Transfer Acceleration?

Answer 1

Amazon S3 Transfer Acceleration involves additional costs compared to standard S3 data transfer fees. Here is a breakdown of the key cost components associated with using S3 Transfer Acceleration:

Cost Components:

1. Transfer Acceleration Data Transfer Fees:

   • Accelerated Data Transfer In (to Amazon S3):
     • Data transferred from the internet to an S3 bucket using Transfer Acceleration incurs a per-GB fee.
   • Accelerated Data Transfer Out (from Amazon S3):
     • Data transferred from an S3 bucket to the internet using Transfer Acceleration also incurs a per-GB fee.
     • Data transferred between S3 buckets using Transfer Acceleration within the same AWS Region or between regions incurs a per-GB fee.
   • Data Transfer between AWS Regions:
     • Data transfer between different AWS regions using Transfer Acceleration incurs charges.

2. Standard S3 Storage and Request Fees:

   • Apart from Transfer Acceleration fees, standard S3 storage and request fees still apply. This includes costs for storage, PUT/GET requests, and data retrieval.

Example Pricing (as of last update):

(Note: The following prices are illustrative and should be confirmed on the AWS pricing page as they can change over time)

• Accelerated Data Transfer In (to S3)
  • $0.04 per GB transferred.
• Accelerated Data Transfer Out (from S3)
  • $0.04 to $0.08 per GB, depending on the destination and volume of data.
• Data Transfer between AWS Regions
  • $0.04 per GB for data transferred between regions using Transfer Acceleration.

Billing Example:

Suppose you have an S3 bucket with Transfer Acceleration enabled and you upload 100 GB of data from your on-premises location to this bucket. The costs would be calculated as follows:

1. Accelerated Data Transfer In:
   • 100 GB x $0.04/GB = $4.00

If you then download 50 GB from the S3 bucket to a client using the accelerated endpoint:

2. Accelerated Data Transfer Out:
   • 50 GB x $0.08/GB (assuming the highest rate) = $4.00

Additional Notes:

• The actual costs can vary depending on the volume of data and specific AWS region.
• Users should regularly check the AWS Pricing page for the most current and detailed pricing information.
• AWS provides a cost calculator to estimate your costs based on specific use cases and data volumes.

Best Practices:

• Cost Monitoring: Use AWS Cost Explorer and AWS Budgets to monitor and control spending.
• Evaluate Necessity: Use Transfer Acceleration for scenarios where the speed of data transfer justifies the additional cost, such as for large files or latency-sensitive applications.
