The SFTP Gateway is a proxy server that provides a secure and convenient way to upload and download files from S3 buckets over the SFTP and SCP protocols. Manage access through IAM users and authenticate with the SFTP Gateway using IAM user credentials. No separate user management is necessary.

This implementation is unique because it does not buffer files on the local EBS volume. Instead, files are streamed directly to and from S3. This eliminates disk IO as a potential bottleneck for throughput and allows terabyte-sized files to be transferred efficiently. The SFTP Gateway can be deployed in public and private VPCs to serve both external users as well as clients connecting from a corporate network.
