Research on new cloud storage service model
一种新的云存储服务模型研究*

It is an important research field to enhance storage service survivability with network survivability theory. In this paper, a new survivable cloud storage service model is proposed, and the structure of the model is designed and constructed in detail. Then a storage service survivability evaluation method (resource allocation failure probability model) based on probability models is adopted to analyze the service model. The fully evaluation can justify that the cloud storage service model can satisfy survivability.
