摘　　要：阐明云计算和SOA之间的关系对两者的应用和结合有着重要的意义。在对SOA和云计算之间关系进行综述的基础上,分析了SOA与云计算之间的区别和联系,归纳了企业界对二者关系的不同观点,总结了学术界对二者关系的研究现状,提出了采用SOA来整合云服务的思路和方法。首先说明了二者存在融合的可能和必要,并且分析了二者主要的融合点。然后对二者融合面临的机遇和挑战进行了分类,并分析了解决这些问题的途径。最后提出具体的整合需求,并分别介绍了利用SOA整合SaaS和PaaS的方法,对将来进一步具体实现利用SOA技术来整合SaaS也作了展望。Clarifying the relationship between cloud computing and SOA is significant to the application and combina tion of them. This paper surveyed their relationship, and on this basis, the differences and relations between cloud com- puting and SOA were analyzed. In addition, different views from enterprises and the latest academic researches about their relationship were summarized,and the approaches combined with SOA to integrate cloud services were proposed. First, it＇s possible and essential for them to combine. Furthermore, the main combinations between them were analyzed. Second, this paper divided possible opportunities and challenges of combinations into several groups discussed in detail respectively. Additionally, the methods to solve these problems were further analyzed. At last, concrete integration needs were proposed,and the integration methods of SaaS and PaaS by adopting SOA were introduced respectively. Further work of realizing the integration of SaaS by adopting SOA was also discussed.
