Abstract

Data management is one of the key issues in Cloud Computing. This paper proposes a peer-to-peer storage system, called Peeraid, for the clouds that are structured as a collection of peer nodes which are supplied by different participants around the world. Peeraid is highly scalable because data object and node lookups are accomplished by distributed hash table (DHT). User files are stored as erasure-coded shares to achieve high data availability with less storage cost. Peeraid also supports distributed group management in a fully decentralized manner, and utilizes group locality and network proximity to improve access performance. Besides, write operations are efficiently logged to support fast update.
