AWS Transfer Family is a secure file transfer service designed to enable seamless transfer of files into and out of AWS storage services. It supports both Amazon S3 and Amazon EFS, making it an ideal solution for migrating data from on-premises data centers to the cloud. AWS Transfer Family is distinct from other services like DataSync. While DataSync primarily focuses on data migration, AWS Transfer Family delivers a fully managed, highly available FTP server. This means you no longer need to set up and manage your own FTP infrastructure. The service supports multiple protocols including SFTP, FTPS, FTP, and AS2, all while eliminating manual server configuration and maintenance.
AWS Transfer Family handles the infrastructure setup, ensuring high availability, scalability, and robust security. This allows you to concentrate on your core business needs instead of managing servers.
When setting up AWS Transfer Family, AWS provides a public access endpoint for the FTP server, allowing access over the internet. If your requirements demand restricted access—such as internal resources within a specific VPC—you can configure the service to use a VPC endpoint. In addition, files can be directly transferred to S3 or EFS, and Amazon CloudWatch integration offers comprehensive logging and monitoring capabilities.

The AWS SFTP Connector enhances the capabilities of AWS Transfer Family by enabling secure communication with remote servers—be they in the cloud or on-premises. This integration facilitates the merging of externally generated and stored data with AWS-hosted data warehouses, supporting robust analytics, business applications, reporting, and auditing.

From an integration standpoint, AWS Transfer Family works seamlessly with S3 and EFS by directly copying files to these services. This smooth integration with AWS storage options, along with its support for multiple transfer protocols and robust CloudWatch logging, positions AWS Transfer Family as a versatile and efficient solution.
