GraphHopper is able to handle world wide coverage for the Openstreetmap road network. It needs approximately 20GB RAM for the import and approximatly 4 hours (plus 26h for contraction). If you can accept slower import times this can be reduced to 14GB RAM - you'll need to set osmreader.dataaccess=mmap. Keep in mind that this option should not be used for you final web service!
Then, to run the web service with this world wide graph 'only' 13GB are necessary. Without contraction hierarchy this would be about 8 or 9GB, depending on how long queries you allow.
