Abstract

Base platforms for many data-intensive applications start to move onto cloud computing services. These applications inherently requires very large storage space, and append-only distributed file systems have been developed for this purpose. These distributed file systems are capable of running on commodity hardware and highly scalable. Cloud computing service providers only try to reduce management costs, but not concerning about significant up-front investment costs. Additionally, virtual machine technologies, especially Xen that most of cloud computing services use, have low I/O performance. In this paper, we present a cost-effective cloud storage service model, which are built with old PCs but shows good performance. Our experimental evaluation shows 46% better performance in Postmark benchmark.
