Motivation and Prior Work

Quorum systems are constructions used to ensure consistency and availability of data stored in replicated servers. These systems usually comprise a static set of servers that provide a fault-tolerant read/write (r/w) register accessed by a set of clients. This approach is not adequate for long lived systems since, given a sufficient amount of time, there might be more faulty servers than the threshold tolerated, affecting the system correctness. Moreover, this approach does not allow a system administrator to deploy new machines or replace old ones at runtime and cannot be applied in many systems where, by their very nature, the set of processes that compose the system changes during its execution.
