Oh, okay, oh dear, sorry - I've missed the point and feel like a fool
So the servers in question are local to each other, that's a good place to start. Now I think I understand better your need. Sadly, it depends .......
I think that there are three main options:-
- Copy files on completion to FTP server
There is the cost of disk and the time taken to perform the copy. Your choice of copy tool depends on how much data is being written each time. If the files are entirely new, then rsync will not gain much (if anything) over an scp/sftp
.
- Share disk from App server to FTP server
There is a delay each time the file is read because the FTP server will pull it over the network. Implementing this and using the files will be quite easy though
.
- Share disk from FTP server to App server
There is a delay as the file is being written because the App server will have to write over the network. Implementing this and using the files will be quite easy though
There will be a network lag to be taken whichever you choose so none of them are 'free' so it boils down to your choice. I would suggest option 3 is probably safest but it really depends on the amount of data written. There are a few risks though:-
- You might be writing large files that are never used, so you take the pain without actually getting any benefit, so you have to be careful not to just write everything across the network.
- Ensuring you get atomic updates is important too, so write to a temporary file then rename it once complete.
Does this help clarify things, or are you still unsure? Sorry, that I'm all questions.
