As developers, we often face unique challenges when working with cloud platforms. Recently, I had to deal with an interesting issue—downloading a file generated on the fly within a Heroku server. Since Heroku’s filesystem is ephemeral, retrieving the file wasn’t as straightforward as it seemed.

In my latest article, I share how I solved this problem using Net::SFTP to upload files securely to another FTP server, ensuring smooth and efficient file transfers even in the ephemeral Heroku environment.
