As part of the modernization journey, you can face the challenge of transferring files between your on-premises servers and the Amazon Web Services (AWS) Cloud. Transferring data from mainframes can be a significant challenge because mainframes typically can’t access modern data stores like Amazon Simple Storage Service (Amazon S3), Amazon Elastic Block Store (Amazon EBS), or Amazon Elastic File System (Amazon EFS).
Many customers use intermediate staging resources, such as on-premises Linux, Unix, or Windows servers, to transfer files to the AWS Cloud. You can avoid this indirect method by using AWS Transfer Family with the Secure Shell (SSH) File Transfer Protocol (SFTP) to upload mainframe files directly to Amazon S3.
