A company has an on-premises application that uses SFTP to collect financial data from multiple vendors. The company migrated to AWS and has an application that uses Amazon S3 APIs to upload files, but some vendors use legacy systems that only support SFTP. The company wants a managed service solution with the least operational overhead so those vendors can continue uploading via SFTP. Which solution meets these requirements?

AWS Transfer Family provides fully managed support for SFTP, FTPS, and FTP, allowing you to seamlessly migrate your file transfer workflows to AWS. It directly integrates with Amazon S3, enabling vendors to upload files via SFTP directly into S3 buckets without managing any servers. This offers the least operational overhead as it's a managed service. Incorrect options: AWS DMS is for database migration, not file transfer from SFTP. Running an SFTP server on an EC2 instance requires managing the server, patches, and security, increasing operational overhead. Amazon S3 File Gateway provides an SMB or NFS interface to S3, but the vendors require SFTP, not SMB.
