Hidden Data Transfer Costs

Some AWS services may incur data transfer charges that aren’t immediately obvious. For instance, using AWS Lambda to process data in S3 can result in data transfer charges if the Lambda function and S3 bucket are in different regions.

Impact of Network Design on Costs

Your network architecture can significantly impact data transfer costs. For example, using a hub-and-spoke model with a central VPC peered to multiple other VPCs can lead to inter-availability Zone data transfer charges that might be avoidable with a different design.

Understanding these nuances of AWS data transfer pricing is crucial for accurate cost estimation and optimization. In the following sections, we’ll explore specific pricing details for different types of data transfer and discuss strategies to minimize these costs.

Types of Data Transfer

Inbound data transfer

This involves moving data from external sources into AWS services. For example, uploading files to Amazon S3 buckets or importing databases into Amazon RDS.

Inbound data transfer to most AWS services is typically free. This encourages users to move their data into the AWS ecosystem.

Example: Uploading 1TB of data from your on-premises server to an Amazon S3 bucket incurs no data transfer charges.

Outbound data transfer

This occurs when data is sent from AWS services to external destinations, such as delivering content to end-users or backing up data to on-premises systems.

AWS data transfer fees are primarily associated with outbound traffic. The pricing varies based on the total amount of data transferred out of AWS to the Internet.

Tiered Pricing Structure

1. First 1GB per month: Free
2. Up to 10TB per month: $0.09 per GB
3. Next 40TB per month: $0.085 per GB
4. Next 100TB per month: $0.07 per GB
5. Over 150TB per month: Contact AWS for custom pricing

Inter-region data transfer

This involves moving data between different AWS regions, like transferring data from the US East (N. Virginia) to the EU (Ireland).

Moving data between different AWS regions incurs charges. These fees help cover the costs of AWS’s global network infrastructure.

Example: Transferring 100GB of data from the US East (N. Virginia) to the EU (Ireland) would cost approximately $2.00.

Intra-region data transfer

This refers to data movement within the same AWS region, such as between different Availability Zones or AWS services in the same region.

Data transfer within the same AWS region is generally free between most services. However, there are some exceptions.

Exceptions to Free Intra-Region Transfer
