![]() ![]() To help you visualize how this all fits together, here’s a diagram that shows the various types of data transfer for EC2 instances. Data transfers within the same region but crossing availability zones have associated costs. Data transfer within regionsĭata transfer charges between AWS services within a region depend on whether you’re transferring data within or across AZs.ĭata transfers are free if you remain within a region and the same availability zone, and you use a private IP address. In other words, you only pay for the outbound transfer of the originating region, not the inbound transfer in the target region. These costs also depend on the region, but data transfer into an AWS region from any other AWS region is free. Transferring data between AWS services across regions has the same cost structure (although the rates are a lot lower) as transferring data between AWS and the internet. Within AWS, you can transfer data across regions or within a region. However, if a resource is located in the South America (São Paolo) region, the first 100 GB per month is still free, but the next 9.999 TB per month costs $0.15 per GB. For example, for resources located in the US West (Oregon) region, the first 100 GB per month is free, and the next 9.999 TB per month costs $0.09 per GB. Data transfer between AWS and the Internetĭata transfer rates from AWS out to the internet are highly dependent on the region. Other times, there will be a cost to transfer data in and transfer data out, such as when transferring data between EC2 instances in different availability zones (AZs) of the same region.Īll those variables mean that controlling data transfer costs means knowing exactly how your data is moving around. Sometimes there will be a specific cost to move data one way (out) but not the other way (in), such as when transferring to and from AWS S3 across different regions. Sometimes this means that there won’t be a distinct data transfer cost in either direction, such as with Amazon Kinesis. Within AWS between services, such as EC2 or S3įor some AWS services, the cost for moving data in or out is accounted for in the cost of the service itself, rather than billed as a separate data transfer fee.What Are AWS Data Transfer Costs?ĪWS data transfer costs are what AWS charges to transfer data either: You need to understand data transfer charges and what you can do to minimize them. Utilizing the cloud improves your data’s mobility and flexibility to enhance its value, but AWS data transfer costs can add up quickly. Your data is one of the most valuable assets your company has. ![]()
