Triton: a peer-assisted cloud storage system

Abstract

In these days, we are witnessing the evolution of cloud storage systems. One of the most intriguing research branches is focusing on merging these systems with peer-to-peer (P2P) networks, absorbing their benefits and thus creating new hybrid architectures. In this work, we present Triton, a peer-assisted cloud storage system designed to reach fast operations on users' data. By taking advantage of a direct communication channel among users, performed via the P2P network that interconnects all of them, Triton reaches two main goals. First, provides an acceleration on sharing operations and second, reduces the level of trust users must give to the cloud storage providers. Our solution also improves consistency constraints on users' data and reduces the latency requested to reach an agreement among peers. In the experimental results, we show how our prototype widely enhances the bandwidth usage for data sharing operations and also achieve important reduction on latency for the agreement operations.
