Summary on Grant Application Form
We envisage a global storage infrastructure that approximates a Utopian set of ideal characteristics: unbounded capacity; zero latency; zero cost; complete reliability; location independence; a simple interface for users; complete security; and provision of a complete historical archive. Clearly such a vision is not realisable in practice. Our approach to engineering a useful approximation involves designing a write-once log-structured storage layer operating above a peer-to-peer overlay network. Content-based addressing can be used to achieve location-independent access to data; replication of data in the right place, at the right time can be used to achieve reliability and low latency.Such an architecture is highly dynamic: data flows around the system in response to: changes in users' location and behaviour; changes in the access patterns of processes; changes in the physical resources allocated to the system; or changes in the topology of the physical infrastructure. It is essential for the underlying policies to evolve in response to such changes, but the complexity is such that it is infeasible for this to be controlled by human users or administrators. The system must therefore be autonomic, managing such changes automatically.
