Transfer Acceleration Overview

Transfer Acceleration is the new Amazon S3 feature that allows you to significantly increase uploading speed.

According to the AWS Blog, Improvements are typically in the range of 50% to 500% for cross-country transfer of larger objects, but can go ever higher under certain conditions.

Transfer Acceleration is built on top of the existing AWS edge network, which is present in more than 50 locations, and is already utilized by Amazon CloudFront and Route 53.

Once enabled, your uploads will be routed to the best AWS edge location based on latency. Transfer Acceleration will then send your uploads back to S3 over the AWS-managed backbone network using optimized network protocols.
