面向SaaS应用的SMTDM可伸缩多租户数据管理框架

云计算是一种可以弹性并按需提供资源的技术.在多租户共享数据存储模式下，如何实现数据的动态伸缩存储是云数据管理的关键.针对SaaS应用如何随着租户数量及请求规模的变化而进行自适应伸缩的问题，在分析数据存储层的伸缩性需求的基础上，基于Walraven等人提出的多租户架构思想，扩展典型的云应用架构，设计了一个多租户数据管理框架，实现存储资源的弹性.基于该框架，开发了一个面向网络管理领域的SaaS原型系统，验证了其有效性和可用性.

Scalable Multi-Tenancy Data Management (SMTDM) Framework for SaaS Aplications

Cloud computing is a technology that enables elastic, on-demand resource provisioning. In multi-tenant shared data storage model, how to achieve dynamically scalable data storage is the key of cloud data management. For the issue of how SaaS applications adaptively scale with the change of the quantity of tenants and request, on the basis of analyzing scalability requirements of the data storage layer, based on Walraven et al. proposed multi-tenant architecture, we extend the typical cloud application architecture, and design a multi-tenant data management framework, achieving scalability of storage resources. Based on the framework, a SaaS prototype system for network management is developed, verified its validity and availability.
