Scalability and I/O efficiency are two of the biggest challenges in building cloud storage system, especially to the data-intensive applications that will run on cloud. To cloud computing, constructing a suitable architecture for every kind of cloud service is the key to succeed. But very little work has been done to create a valid and standard cloud storage architecture. In this paper, a four-layer cloud storage architecture is proposed. To meet the requirements of data-intensive applications, an efficient and scalable node organization model is introduced to the cloud storage system.
