云平台应用系统迁移方法的研究

Study of Methods for the Cloud to Migrate Application Systems

针对多组件应用系统迁移到云平台的目标物理服务器的选择问题,提出了一种基于组件间通信量的迁移方法。迁移方法根据形式化后的应用系统逻辑架构图和云平台物理资源组织结构图,通过计算组件间的通信量和虚拟资源需求值,为应用系统各组件在云平台选择目标物理服务器。通过在品高云计算平台上的多租户精品课程网站群系统的迁移实验,证明了所提迁移方法较好地减少了应用系统在使用时,云平台内部物理服务器间的通信量。

Regarding the problem of selecting target physical servers when migrating multi-component application systems to the cloud, a migration method based on the inter-component communication amount was proposed. According to the formalization of the application system logical architecture and cloud platform physical resources organizational structure, the method is to select target physical server for each system component by calculating the communication amount and virtual resource requirements of them. By the experiment of migrating multi-tenancy excellent course websites system to Bingo Cloud, the result shows that the migration method can reduce the traffic between physical servers of the cloud platform.
