云计算的开放架构设计

云计算作为IT基础设施的提供者,必须提供开放接口才能够获得广泛使用,否则只是专用系统而不能称为云计算。文章从云计算各个层面,包括基础设施即服务(IaaS)、平台即服务(PaaS)、软件即服务(SaaS)讨论了服务开放的实现方式,并提出了如何处理开放引发的安全及升级问题的解决方案。最后指出利用开放的云计算服务可以给传统的电信服务发展带来新的契机。

Open Architecture Design of Cloud Computing

As the basis of IT infrastructure, cloud computing has to provide open interface for widespread use otherwise it is just a dedicated system. This paper discusses the implementation of open service from all levels of cloud computing including Infrastructure as a Service （IaaS）, Platform as a Service （PaaS）, and Software as a Service （SaaS）. Solutions are proposed for security and upgrading in an open service environment. In conclusion it is proposed that open cloud computing can bring about many development opportunities for traditional telecom services.
