构建云计算平台的开源软件综述

Survey of Open Source Software for Building Cloud Computing Platforms

云计算开源软件的涌现为云计算平台的构建提供了便利,同时也为人们从中选择合适的软件带来了挑战。为明确如何构建云计算平台,研究现有用于构建云计算平台的开源软件十分必要。考察构建云计算平台的开源软件的发展状况,从提供服务的角度对各种服务模型的开源软件体系结构进行剖析,通过对比分析当前典型的用于构建云计算平台的开源软件,来为云计算平台建设者利用此类软件构建符合特定需求的云计算环境提供有效的途径。

The emergence of open source software for cloud computing facilitates the building of cloud computing platforms,but meanwhile it challenges the choosing of appropriate ones from these pool of software.To figure out how to build a cloud computing platform,research on existing open source software for building cloud computing platforms is necessary.This paper investigated the development of these kinds of open source software and analyzed their architectures from the perspective of service models.Through comparison and analysis of representatives of them,effective ways were proposed for developers to choose appropriate pieces of software to build a specific cloud computing platform.
