Create/send a file to FTP server via ABAP cloud or use SAP CPI

Hi,

With on-premise, it was relatively easy to create files and transfer them to our AL11 directories. However, in the public cloud, most of the references that I found asks me to create an iflow where I call an odata and use an FTP receiver adapter to transfer the file.

Now I am just wondering if it's even possible/advisable to create/send the file via an program? The blog below shows how to do it via HTTP API classes assuming that the SFTP server provides a REST API.

I would like to know what is the best practice way to achieve it in the public cloud. Thanks.
