基于OpenStack的清华云平台构建与调度方案设计

从一般云计算的体系结构与清华大学的实际需求出发，利用先进的OpenStack平台，采用分层设计的方法设计实现一个可对云资源进行综合管理的清华云平台。分析了该系统的优势和应具备的主要模块功能，重点研究系统中的资源调度关键技术，提出了一种基于任务调度和负载均衡的策略，并通过对调度方案的实验与分析，验证了该调度策略在保证服务性能和执行效率的基础上能够均衡服务器的资源负载，使云平台处于相对稳定的状态。

Architecture and scheduling scheme design of TsinghuaCloud based on OpenStack

Based on cloud computings architecture and the actual demands of Tsinghua University, followed by utilizing the advanced OpenStack platform, adopting hierarchical design method, the TsinghuaCloud platform that could be used to perform integrated management on cloud resources was designed and implemented. The advantages and main required module functions of this system were analyzed. Focusing on the resource scheduling, a strategy based on task scheduling and load balancing was proposed. The experiment and analysis of the scheduling plan verify that the scheduling strategy can balance servers resource load on the basis of ensuring its service performance and execution efficiency, so as to make the cloud platform relatively stable.
