Abstract

The importance of service-oriented architecture for science is widely recognized. Increasingly, scientific communities are making information tools accessible as services that clients can access over the network, without knowledge of their internal workings. In this way, tools formerly accessible only to the specialist can be made available to all. Equally importantly, new value-added services can be constructed that integrate other services to automate useful tasks. The value of such service-oriented science has been demonstrated in disciplines as diverse as astronomy, biology, and fusion science. The mechanisms required to achieve these goals are provided, in part, by grid infrastructure. I review the mechanisms that have been developed to date for grid infrastructure and experience gained implementing these mechanisms, for example within the open source Globus Toolkit version 4. I present a range of dynamic service deployment scenarios, in which for example the TeraGrid and Open Science Grid are used to host services for science communities. I discuss how these scenarios demonstrate the potential for scaling service-oriented science

面向服务的科学:扩展研究的应用和影响
面向服务的体系结构对科学的重要性已得到广泛认可。科学界越来越多地将信息工具作为服务提供给客户,使其可以通过网络访问,而无需了解其内部工作原理。通过这种方式,以前只有专家才能使用的工具可以向所有人开放。同样重要的是,可以构建新的增值服务来集成其他服务以自动执行有用的任务。这种以服务为导向的科学的价值已经在天文学、生物学和融合科学等多种学科中得到了证明。实现这些目标所需的机制部分由网格基础设施提供。我回顾了迄今为止为网格基础设施开发的机制以及实现这些机制所获得的经验,例如在开源的Globus Toolkit版本4中。我提出了一系列动态服务部署场景,例如使用TeraGrid和Open Science Grid为科学社区提供服务。我将讨论这些场景如何展示扩展面向服务的科学的潜力
