It became apparent that this method could be a maintenance challenge, so I started thinking of alternate approaches. Oh, and if a customer added a PC or two to their business, I’d also have to deploy the scripts there as well. Then of course if the script ever needed to be changed, I’d have to change it and re-deploy it 10 times. I mean, the script would be same I’d just have to set it up on 10 different PCs. FTP still seemed like a logical choice at this point. Surely that would work, but as I thought about it more, it would require me to create an FTP script and deploy it to each of the ten clients. Recently, I was working on a project that required many customers (around 10) to send a CSV document to my client so it could be processed on their IBM i.

These methods work great for a peer to peer transfer and are also sufficient in a peer to many peer model. However, what if you wanted to exchange a CSV, PDF or Word document? Typically FTP or SFTP come to mind as solutions. Sharing data is a vital part of most businesses today and it seems the need is growing more each day. Web services have become a popular way to transfer data in XML or JSON format and they work great.
