AWS Transfer Family SFTP connectors
AWS Transfer Family SFTP connectors establish a relationship for sending files and messages between Amazon storage and an external partner, using the SFTP protocol. You can send files from Amazon S3 to an external, partner-owned destination. You can also use an SFTP connector to retrieve files from a partner's SFTP server.
Note
Currently, SFTP connectors can only be used to connect to remote SFTP servers that offer an internet accessible endpoint.
The following video provides a brief introduction to Transfer Family SFTP connectors.
