AWS Transfer Family

AWS Transfer Family is a fully managed service that allows customers to transfer files over SFTP, FTPS, and FTP directly into and out of Amazon S3. It eliminates the need to manage any infrastructure for file transfer, which reduces operational overhead. Additionally, the service can be configured to use an existing Active Directory for authentication, which means that no changes need to be made to the customer's application.
