Palimpsest: Soft-Capacity Storage for Planetary-Scale Services

  title={Palimpsest: Soft-Capacity Storage for Planetary-Scale Services},
  author={Timothy Roscoe and Steven Hand},
Distributed writable storage systems typically provide NFS-like semantics and unbounded persistence for files. We claim that for planetary-scale distributed services such facilities are unnecessary and impose an unwanted overhead in complexity and ease of management. Furthermore, wide-area services have requirements not met by existing solutions, in particular capacity management and a realistic model for billing and charging. We argue for ephemeral storage systems which meet these requirements… CONTINUE READING
