Distributed Objects (Background). The . message-passing . paradigm is a natural model for distributed computing, in the sense that it mimics inter-human communications. It is an appropriate paradigm for network services where processes interact with each other through the exchanges of messages. . Set up a large number of machines all identically configured. Connect them to a high speed LAN. And to the Internet. Accept arbitrary jobs from remote users. Run each job on one or more nodes.
