摘　　要：云计算是一种将计算和存储任务分配到由大量计算机构成的云中的计算模式。云计算提供三种类型的服务:基础设施服务(IaaS)、平台服务(PaaS)和软件服务(SaaS)。虽然PaaS在云系统中起到了关键的作用,但是目前的PaaS平台存在着服务协同性低、资源匮乏、用户界面不友好等问题。设计并实现了基于准则调控和策略驱动的自治式服务协同模型(NGPD)的PaaS平台,其利用自治计算元素实现了自治式服务协同,这是尝试解决现有PaaS平台支持提供云平台型服务不足的探索性研究,为云用户提供了更加高效和经济的平台开发环境。Cloud computing is a computing paradigm that it assigns the computing and storing task to the cloud which is composed by a large number of computers.Cloud computing provides three types of services：infrastructure as a service,platform as a service and software as a service.While PaaS in cloud system plays a key role,there is now PaaS platform for low service coordination,lack of resources,unfriendly user interface and other issues.This paper designed and implemented PaaS platforms based on norm-governed and policy-driven autonomic model of service cooperation,which was using autonomic computing elements to achieve a collaborative self-service and was an exploratory study trying to solve the problems of existing platform to support PaaS,aiming to provide more efficient and economic development environment for the users.
