An overview of newly open-source cloud storage platforms

Cloud storage has been increasing in popularity with cloud computing. It can make a large variety of different storage devices working together over Internet and provide outside access to data storage through the cluster application, grid computing, distributed systems and so on. In this paper, we give insights into the essential characteristics of several open-source cloud storage platforms, including architecture, implementation technology and function features, based on newly open-source cloud computing systems such as Hadoop, abiCloud, Cassandra and MongoDB. Moreover, we compare and contrast their storage functions in order that users can choose the corresponding cloud storage platform by user demand.
