Classic Distributed System Failures
Clock Problems: A subsequent update is applied
to a server with a clock in the past
Data Location Updates: Reads or writes are
applied to a wrong quorum of servers
Buffered Writes: A crash occurs before data is
written to persistent storage
Asynchronous Replication: Data is applied, but
then crashes, other writes are applied, revived
server overwrites
Bugs: A correct architecture, poorly
implemented
