Thanks for your suggestion. As i don't want to own/manage my own AWS environment. Does Adobe S3 at AWS also enabled the AWS S3 sftp service? Then i can directly to send the files via sftp from my on-perm machines.
On top of kunal23's suggestion, you can also leverage AWS S3 sftp service to upload files to your own S3 instance,
and then transfer to Adobe provision S3 through AWS Lambda. Although Adobe doesn't officially support sFTP as the file transfer option(ftp only), S3 has opened up a lot of flexibility for your data file transfer options.
Thanks for your reponse. I should ask how to automate the file transfer from my machine to AAM S3 bucket. Even provsion an S3 account for me, i cannot automate the file transfer from my machine to AAM S3 bucket. I just know i can automate sftp job to do file transfer from my machine. Any option to automate the file transfer from my machine to AAM S3 bucket?
