You can also make use of your existing DNS name and SSH public keys, making it easy for you to migrate to Transfer for SFTP. You can also use IAM policies to control the level of access granted to each user. You can create users within Transfer for SFTP, or you can make use of an existing identity provider. You have fine-grained control over user identity, permissions, and keys. You simply create a server, set up user accounts, and associate the server with one or more Amazon Simple Storage Service (Amazon S3) buckets. Today we are launching AWS Transfer for SFTP, a fully-managed, highly-available SFTP service. We want to help our customers to move these workflows to the cloud in a smooth, non-disruptive way. While it would be easy to dismiss these systems as “legacy,” the reality is that they serve a useful purpose and will continue to do so for quite some time.
Many organizations use SFTP (Secure File Transfer Protocol) as part of long-established data processing and partner integration workflows.
