AWS on FTP-CLIENT

I am new to networking and servers. I want to GET data from the FTP client set up in AWS to the FTP server set up in the company LAN, but the FTP server set up in the company LAN has a local address. Question 1: What should I do to resolve the address? Normally, an FTP client is placed on the company LAN, and FTP communication is performed within the company LAN. After collecting the files, I think it would be good to PUT the data to the FTP server set up in AWS, but I think this is a special case. Question 2: Please tell me the most balanced method and server arrangement.
