Abstract :
This paper proposes a replication cost model and two greedy algorithms, named GS QoS and GS QoS C1, for replication placements in cloud-based storage systems. The model aims to minimize replication cost with full consideration of quality of user access to storage nodes. Our two algorithms employ a utility measurement to guide placement procedures. Our final experimental results show that 1) GS QoS outperforms GS QoS C1, 2) both algorithms have more economical results than those from existing greedy replica placement algorithm.
