Need to use UNIX to access a file from "the cloud"
Normally files are given to us via FTP and we use a program (DMX) to pull that file into our database. I have been told that we will be receiving a new file via "the cloud" and I need to prepare a method to access and otherwise process this file using UNIX/LINUX. I realize my request raises more questions but that's all the information I have. I need to put together and basic list of questions to ask because right now I don't know much about linux beyond running a few executables and changing directories.
What is meant by "the cloud"? I know what the cloud is in a general sense. Should I expect a network address or IP address or webpage or what?
Is it reasonable to ask that this mysterious cloud file be delivered to me via FTP where I can process it as I do all other files?
What commands in linux do I need to familiarize myself with to process this file into a database?
What questions do I need to ask about this file and its location that will help me?
Thanks for your patience.

dmxgetscreencount
DMXGetScreenCount(3X) DMXGetScreenCount(3X)
NAME
DMXGetScreenCount - determine number of back-end screens
SYNOPSIS
#include <X11/extensions/dmxext.h>
Bool DMXGetScreenCount(Display *dpy,
int *screen_count);
DESCRIPTION
DMXGetScreenCount() returns the number of back-end screens that a Xdmx(1) server controls. Since a DMX screen usually fills all of the
available area on a back-end server, there is usually a one-to-one correspondence between DMX screens and backend servers. However, it is
also possible for a DMX screen to cover only part of the available area on a back-end server, and for more than one DMX screens to occupy
different parts of the visible area on the same back-end server.
A DMX screen may be managed as a regular X screen in the Xdmx(1) server or may be joined with other DMX screens using Xinerama.
RETURN VALUE
DMXGetScreenCount() sets screen_count and returns True unless there is a protocol error.
NOTES
If Xinerama is active, only one logical screen will be available to clients of the Xdmx(1) server. However, this call will accurately
reflect the number of composite back-end screens that the Xdmx(1) server is using.
