摘要:
云计算服务平台通过创建软件映像文件的多个复制副本来保证服务部署的高可靠性,但是,过多的副本却导致更新代价的增加。为解决此问题,提出了复制副本分治的策略,即将副本划分为同步副本与异步副本后分别处理。同步副本用来保证服务部署的可靠性,异步副本用来降低更新代价。论文首先给出了基于部分异步复制的云服务部署模型;然后设计了软件映像文件的副本复制算法和异步副本升级算法;最后,对算法进行了模拟评价,得出了同步副本数与异步副本数之间的指导性比例关系。

Abstract:
Aim. Existing methods for service deploy while failure occurs are, in our opinion, not quite have better Availability. We propose what we believe to be a better method. In the full paper, we explain our provide guarantees about the availability of the images deployed for consumption of the distribution services in detail. In this abstract, we just add some pertinent remarks to listing the four topics of explanation. The first topic is:The replicated images subsystem model based on partially asynchronous replication, as shown in Fig.1 in the full paper. In this topic, we discuss the four concept of the model:the interaction between images and deploy services. The second topic is:the replication schema. The third topic is protocol partially asynchronous replication model. In this topic, we present we discuss the four procedures of the model:find of global image name, activate the deployment service, delivere image required and deploy VM. The fourth topic is:an algorithm for promoting the asynchronous replication to synchronous. Finally we do experiments to appraise our method. Table 1 in the full paper shows preliminarily that the deployment service time of our better method based on partial asynchrony strategy is quite efficient in comparison with the methods that use asynchronous and synchronous method. Premise of ensuring availability,the time of the replicas of images decreases by 10%.
Key words:    partial asynchrony    service deployment    deployment store manager    software images    clouding computing    controllers
