摘要
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),其中PaaS云平台主要提供应用的基础服务和托管环境,这些基础服务也可称之为能力组件。传统的PaaS云平台能力组件只能由这个PaaS云的运营商来开发,这势必将大大减少能力组件的多样性。这个又恰恰就是PaaS云的核心差异点,决定着这个平台是否能够在市场上生存下去。本课题就将为PaaS平台的能力组件的开发提出一种新的模式-能力商店,并为此模式提供了一个高可用的通用弹性框架,使得能力开发者只需关注自身的业务逻辑,最终增强能力组件的健壮性、可用性,缩短其研发上线时间。
Cloud computing provides three types of services： Infrastructure as a Service （IaaS）, Platform as a Services （PaaS） and Software as a Service （SaaS）.PaaS Cloud mainly provides application hosting environment and basic services, which can also be called enabler components. The enabler components of traditional PaaS cloud platform could only be developed by platform operators, which is bound to greatly reduce the diversity of enabler components. However, this is exactly the key difference of various PaaS platforms, determining the destiny of one＇s survice in the market. To solve this problem,this paper brings up a new enabler providing pattern named enabler shop.At the same time a highly available generframework is designed so that enabler developer only needs to focus on the components＇s business logic.Furthermore,the component is developed in shorter time with higher robust because of the underlying enabler framework services
