REST: A Reliable and Efficient Storage Technology for Content Cloud Service
Ru Zhang · Dianzi xuebao · 2014
Cloud computing technology incorporates asymmetric hardware equipments and establishes the basis of providing constant and efficient service to the users. In this paper,intrigued from the redundancy backup strategy,we design a cloud storage mechanism which can tolerate hardware or software failures so as to ensure the reliability of the content cloud system while distributing the contents efficiently. Adopting this mechanism,the system can still operate smoothly in the presence of a fixed number of hardware or software failures,and if the number of failures is larger than that,the mechanism can protect the system from massive breakdowns. Afterwards,through experiments we compare several kinds of storage technologies,and validate that our technology takes advantages in storage efficiency and fault tolerance.
