Replication degree customization for high availability

  title={Replication degree customization for high availability},
  author={Ming Zhong and Kai Shen and Joel I. Seiferas},
Object replication is a common approach to enhance the availability of distributed data-intensive services and storage systems. Many such systems are known to have highly skewed object request probability distributions. In this paper, we propose an object replication degree customization scheme that maximizes the expected service availability under given object request probabilities, object sizes, and space constraints (e.g., memory/storage capacities). In particular, we discover that the… CONTINUE READING
