This is a pretty straight forward blog and personal documentation on how to setup a SFTS3 bucket as the backend of the SFTP server. I hope you find this helpful as I did.
Step 1.
Create S3 Bucket from the AWS console. The S3 Bucket will be the place where the files will stay. No custom changes will need to be made to the s3 bucket itself.
Step 2.
Navigate to AWS Transfer Family service and select create Server. Where you will be prompted to select FTP, FTPS, SFTP. Select SFTP, which stands for SSH File Transfer Protocol. SFTP is a network protocol that provides file access, file transfer, and file management over any reliable data stream.
