Data is one of an organization’s most valuable assets. When hosted in AWS, it gives the organization more flexibility and access, enhancing its value. However, AWS data transfer costs between regions can be expensive. Unlike transfers with Availability Zones that tend to be less expensive, transferring outside a region can pile up a lot of money. 

The cost of AWS data transfer across regions is similar to that of transferring between AWS and the Internet. This is because the prices depend on regions. You only pay for the outbound transfer fee for the region you are transferring to.

This article provides insights on how to minimize costs when transferring data from one region to another. 

Plan Your Route

Data transfer costs on AWS can differ significantly. Regional pricing means some regions incur more costs than others. Therefore, the region you choose matters a lot, as some regions are more expensive than others. 

AWS regions within the United States and Canada are the cheapest. On the other hand, Singapore, India, and South American countries tend to be costlier. The best practice is to have lesser, low-cost regions where data flows. Rearchitect the cloud environment, so there is minimal data transfer and only do it between regions that do not incur high costs.

However, it’s best to note that minimizing costs can have an impact on your business decisions. For instance, if you operate a business across different regions, you may have to cut that a bit. 

Use Private IP Addresses

Using Private IP addresses can significantly save on costs. Private IP addresses are less expensive when compared with Elastic IPs or Public IPs. 

Along with a Private IP address, you can cache your data at origin servers. Compress both static and dynamic content by caching the client-side and compressing the server-side automatically.

Consider Services that Reduce Data Transfer

Rather than transferring data directly, you can choose services that enable transfers at lower costs. These services include:

  • Amazon CloudFront
  • VPC Endpoints

Amazon CloudFront is a CDN service that allows users to move massive amounts of data, such as audio, videos, and images, at a lower cost. 

Amazon CloudFront allows data transfer with high speeds and low latency. It works by caching data at edge locations, which minimizes the load on resources. Besides reducing transfer costs, Amazon CloudFront provides HTTPS support, field-level encryption, and integration with other services, such as AWS Shield.

AWS Direct Connect enables you to create an AWS dedicated network connection. This provides a more consistent network than Internet connections that tend to lag at some point. The dedicated connections increase bandwidth and reduce costs.

VPC Endpoints reduce public data transfer by allowing AWS connections with private networks. This reduces Network Address Translation (NAT) gateway costs.

Limit Outbound Data Transfer

While it may be impossible to cut off transfers between regions completely, you can minimize that by choosing the right infrastructure. Architect your applications to keep all transfers within a single AWS region. 

Also, keep EC2 data within a single Availability Zone. All EC2 data transfers within a single Availability Zone, coupled with Private IP addresses, minimize costs. When doing this, you will only incur a cost of 1 cent per GB.


It’s best to use the resources that incur lesser costs to minimize AWS data transfer costs between regions. With the right resources, you will end up saving hundreds to thousands of dollars.
