Recently, the term cloud computing is widely used in the searching community, which shows the importance given by the scientists to this research area; cloud computing is a new computing model provides shared resources and data based on service delivery model, where everything from infrastructures, platforms, and software are given to the user like a set of services. The users of cloud platforms deal with these services to satisfy their requests, however these requests become more complex, and they need more than one service to accomplish one request; the process of gathering a set of services to satisfy a user request is called the service composition. In addition to the fact that one request needs a set of services to be executed, and die to the quick development of cloud technology, there are many of similar services which offer the same functionality, for each service in this set, which make the composition process needs a mechanism to choose between these infinity choices to give the user an optimal satisfaction. In this paper, We propose a framework for service composition in the multi cloud environment where we compose these services based on two factors: the first is a set of QoS (quality of service) criteria for each service, and the second is the number of cloud bases involved in the composition process, to build a composed service that satisfy the user request.

多云环境下基于QoS的Web服务组合框架

最近,云计算一词在搜索社区中得到广泛使用,这表明科学家对该研究领域的重视。云计算是一种新的计算模型,它基于服务交付模型提供共享的资源和数据,其中基础架构,平台和软件等所有内容都像一组服务一样提供给用户。云平台的用户使用这些服务来满足他们的请求,但是这些请求变得更加复杂,并且他们需要一项以上的服务来完成一项请求。收集一组服务以满足用户请求的过程称为服务组合。除了一个请求需要执行一组服务并最终影响云技术的快速发展外,对于此集合中的每个服务,有许多相似的服务提供相同的功能,这使得合成过程需要一种在这些无穷大选择之间进行选择的机制,以使用户获得最佳的满意度。在本文中,我们提出了多云环境中服务组合的框架,其中我们基于两个因素来组合这些服务:第一个是一组针对每种服务的QoS(服务质量)标准,第二个是服务数量云基础组成过程,以构建满足用户需求的组合服务。
