I've been thinking and doing this for many years - I've tried very hard to do it with one diagram without luck if you want them to look nice (and I do try to make them as artistic as possible) then I've found that the best/ only proper way to do it, is to do multiple diagrams for different groups of people. complex/ messy one for infrastructure - showing interfaces/ IP address/ security zones/ resiliance/ physical locations/ application binaries/ OS info etc.. sequence diagrams for logic flow of applications basic fancy ones for stake holders/ less technical ppl - crayon type of diagrams for all the diagrams: I find using matching colours (but try if possible, to consider color blind people) and levels of grey (try not to use black) work best... try to group interfaces close together... try not to have crossing lines... symetrical as possible... lines and boxes all aligned with something
