Amazon S3 Transfer Acceleration

Amazon S3 Transfer Acceleration (S3TA) enables fast, easy, and secure transfers of files over long distances between a customer’s client and an S3 bucket. Transfer Acceleration takes advantage of Amazon CloudFront’s globally distributed edge locations. As the data arrives at an edge location, data is routed to Amazon S3 over an optimized network path. Customers should ensure that any data containing PHI transferred using AWS S3TA is encrypted in transit and at-rest. Refer to the Guidance for Amazon S3 to understand the available encryption options.
