摘要
传统的"双机热备式"服务计算模型具有难以克服的缺陷,很难满足日益流行的服务计算环境中的数据一致性、数据完整性和数据高可用性的要求,本文提出的存储寄存算法摒弃了旧的计算模型中的共享存储,通过在对端节点中寄存自己的一份完整数据拷贝,从而可以更低的价格实现具有更高数据安全性和可用性以及更快切换效率、更高读写性能的服务计算环境。
Traditional hot standby two-node cluster service computing model has major defects, making it difficult to satisfy the requirements of high data consistency, data integrality and data availability in service computing environment. Based on the old model and through getting rid of the share storage, our storage deposition algorithm in this paper can be used in the service computing spot, which requires more serious data security and availability, more efficiently switching, etc. by means of depositing the copy of local data in counterpart real-timely.
