![]() PricingĪny object uploaded through transfer acceleration will be charged based on which edge location is used as the intermediary between the user and the s3 bucket. The AWS console does not make use of transfer acceleration on uploads. Using the endpoint doesn’t guarantee the file will be routed through an edge location. On each request, AWS will determine whether to use transfer acceleration or not based on the performance benefit you may realize. You can point all your PUT and GET requests to the new URL. You can continue to use your regular S3 bucket URL for cases where you do not want to incur the cost of using transfer acceleration. You cannot do something like s3 / bucketname/ filename. The transfer endpoint must have the bucket name as the host. You will need to modify your bucket endpoint, as shown below: Transfer Acceleration works for both object uploads and downloads (PUT/GET requests). Only the bucket owner or a user with the permission PutAccelerateConfiguration can change the state of transfer acceleration for a given bucket.Ĭlick on your bucket, go to properties and click transfer accelerationĬhange the state to enabled and click save.Īfter enabling transfer acceleration, it might take up to 20 minutes until you notice any speed improvements. You can enable transfer acceleration through the console, API, SDK, or CLI. Your data is never stored at the edge location. Using transfer acceleration has the same security guarantees as S3. The API calls are synchronous, which means that you will not receive a success response until the object has reached its final destination, the bucket. Remember that the uploaded object will still need to travel from the edge location to the bucket, but this will happen over an optimized network path. Generally, you will see more acceleration when the source is farther from the destination when there is more available bandwidth, and/or when the object size is bigger.” “The amount of acceleration primarily depends on your available bandwidth, the distance between the source and destination, and packet loss rates on the network path. Here is how AWS describes who will see the most benefit: Cloudfront is usually known as a CDN, but it can also handle file uploads as well. If your files are less than 1GB in size or your total data transfer is generally less than 1 GB, you should use Cloudfront instead. You will also see an increased benefit if your internet connection is not stable, and there is a higher amount of packet loss. Another good rule is that bigger files will generally show more acceleration. The general rule is the further your customers are from your S3 bucket region, the more beneficial transfer acceleration will be to them. The limitation of this tool is that it runs based on your location while you may want to mimic your customers, which may be on the other side of the world. To have the tool focus on a specific region, you can copy/paste the following URL replacing the region with the specific one you are interested in testing. ![]() The tool works by uploading a test object directly to a bucket in 15 different regions with and without transfer acceleration enabled.īy default, the tool will first test the US-Virginia region. PerformanceĪs a starting point, Amazon provides a tool you can use to determine whether you will see an increase in speed with transfer acceleration enabled. ![]() From there, the file will still need to make it’s way back to Virginia, but AWS will use an optimized network path to speed up the transfer between the edge location and the S3 bucket. With transfer acceleration enabled, the data will only need to travel to a local edge location in Australia. When uploading a file, the file will need to travel from Australia all the way to Virginia. Imagine we have an S3 bucket located in Virginia, but our customers are on the other side of the world in Australia. Here are some high-level statistics from AWS:īelow is a map of the AWS edge locations versus regions: AWS has only 24 regions but has 216 edge locations The user performing the upload will be uploading to his nearest edge location instead of directly to the S3 bucket. An edge location is a data center located close to your customers, which provides low latency access to cached content. It works by utilizing Amazon’s global network of edge locations, the same infrastructure used by other AWS services such as Cloudfront and Route53. Transfer acceleration is a way to speed up both uploads and downloads with your S3 bucket.
