Sorry, but I really do not understand what you ask for.
I have been using AWS managed server which was powered by Cloudways and it's been working fine for me and the file transfer is very simple and secure as they have an option of sftp in their platform.
However, I am now looking to do it myself as I want to dig out the process of setting up the aws instance and file transferring through WinSCP and then the other related stuff. I have gathered sound knowledge of the process of setting up AWS instance and I am still learning about Amazon AWS. Similarly, I was thinking if I could find any guide or tutorial on WinSCP.
