What is Peer-to-peer? Hub-and-Spoke network Hub-and-spoke: - centralized - Single point of failure - cost of a server - adding more clients make network slower Centralized server-based service model. - need failover and backups P2P network P2P - decentralized - adding more clients make network faster - robustness, no failover A peer-to-peer system of nodes without central infrastructure. ® Source: Wikipedia.org Copyright 2009 Adobe Systems Incorporated.
