When moving a server application that is running on the same system that a client application is running on to a completely different machine that happens to also be running Linux OS, we must consider the following; 1) The other system must be reachable by the client 2) The port number at which the server is listening should be available in the new system. In case the port number is hard coded, we need to update it and if is a command line argument input we can always start the server with new port number. 3) The client application to be updated with the IP of the new machine in case it is hard coded in the system or the port number (in case it is changed). If IP and port number are command line inputs than we can just start the client with the new IP and port number.

What would be the considerations if this different system is on the local area network (LAN)?

What would be the considerations if this different system was in the cloud?

What are the advantages of distributing the server application in this way?
