Sorry to tease, but it's amusing to me that you are technically competent enough to upload files to a data center, but don't know how to do the easier task of networking two computers (presumably) in the same room. Seriously, though, if the computers are (or can be) on the same network, then there are dozens of ways to achieve this. The easiest is probably shared network directories, but there's also NFS, rsync, scp, FTP, etc. IF the machines are on different networks it can be a little more work, but still not hard.
