The paper, "Chord: A Scalable Peer-to-peer Lookup Service for Internet Applications", clearly answers what is perhaps one of the most important questions in computer science, "Does it scale?" I like the whole idea of distributed scalable systems. The paper offered a strong theoretical foundation for the proposed method. The method scales very well and is robust to node failures. I have been trying to think of some constructive criticism, but have not been successful.
One question I have is, How does cloud computing work today? Is it based on something like Chord? What advantages could a more centralized hash table have over Chord, given that the centralized solution scales just as well?
I think that's just it: the centralized solutions just can't scale like the distributed systems can.
