【摘要】 对SaaS模式下,对共享模式的多租户数据在云中多节点环境的划分问题进行了研究,提出一种支持SaaS应用的多租户数据划分模型和算法。与目前主要面向分析型应用并且缺乏事务支持的分区技术和云数据库解决方案进行比较,理论分析和实验结果同时表明,该划分机制能有效地实现云环境中系统规模动态扩展,同时最大限度地降低分布式事务代价。更多还原

【Abstract】 In SaaS model,the multi-tenant data using shared schema partitioned in multiple nodes of the cloud environment was put forward in advance.Based on this,a data partition model and algorithm for multi-tenants to support SaaS application was proposed.Through comparsion with many data partition technology and cloud database solutions mainly for analysis application and lack of transaction support,the theoretical analysis and experimental results reveal that the proposed data partition mechanism can effectively realize the dynamic scalability of the system in cloud environment,at the same time to minimize the cost of the distributed transaction.更多还原
