Creating a remote front panel for a LabVIEW application will allow a user to view and control the VI from a web browser. The VI itself will run on the host computer, but it will read data from and write data to the web server which hosts the web page. If you have specified for your VI under VI Properties >> Window Appearance that the Run button should be visible, then viewers of the remote front panel will have the ability to run the VI if it is not already running, since they will see the run button on the web page. The VI only has to be open (i.e. loaded into memory) to be viewed from the remote front panel.
If I were you, I would create a very simple VI for test purposes only and go through the steps in the document linked above. It's really a short process, and this would allow you to play around with it and see what it can do. I hope this helps!
