AWS Transfer Family introduces additional configuration options for SFTP connectors

[AWS Transfer Family](https://aws.amazon.com/aws-transfer-family/) announces new configuration options for SFTP connectors, providing you more flexibility and performance when connecting with remote SFTP servers. These enhancements include support for OpenSSH key format for authentication, ability to discover remote server’s host key for validating server identity, and ability to perform concurrent remote operations for improved transfer performance. SFTP connectors provide a fully managed and low-code capability to copy files between remote SFTP servers and Amazon S3\. You can now authenticate connections to remote servers using OpenSSH keys, in addition to the existing option of using PEM-formatted keys. Your connectors can now scan the remote servers for their public host keys that are used to validate the host identity, eliminating the need for manual retrieval of this information from server administrators. To improve transfer performance, connectors can now create up to five parallel connections with remote servers. These enhancements provide you greater control when connecting with remote SFTP servers to execute file operations. The new configuration options for SFTP connectors are available in all [AWS Regions](https://docs.aws.amazon.com/general/latest/gr/transfer-service.html#transfer-region) where the Transfer Family is available.
