本文介绍了e-Science Central (e-SC)云数据处理系统及其在若干e-Science项目中的应用。e-SC提供软件即服务(SaaS)和平台即服务,用于科学数据管理、分析和协作。它是一个便携式系统,可以部署在私有云(例如Eucalyptus)和公有云(Amazon AWS和Microsoft Windows Azure)上。这款SaaS应用程序允许科学家上传数据,编辑和运行工作流,并在云中共享结果,只需要一个Web浏览器。它由一个可扩展的云平台支撑,该平台由一组旨在支持科学家需求的组件组成。该平台向开发人员开放,以便他们可以轻松地将自己的分析服务上传到系统中,并使这些服务可供其他用户使用。还提供了基于表示状态传输的应用程序编程接口(API),以便外部应用程序可以利用平台的功能,从而更容易构建可扩展的、安全的基于云的应用程序。本文介绍了e-SC的设计、API及其在三个不同案例研究中的应用:光谱数据可视化、医疗数据捕获和分析以及化学性质预测。
This paper describes the e-Science Central (e-SC) cloud data processing system and its application to a number of e-Science projects. e-SC provides both software as a service (SaaS) and platform as a service for scientific data management, analysis and collaboration. It is a portable system and can be deployed on both private (e.g. Eucalyptus) and public clouds (Amazon AWS and Microsoft Windows Azure). The SaaS application allows scientists to upload data, edit and run workflows and share results in the cloud, using only a Web browser. It is underpinned by a scalable cloud platform consisting of a set of components designed to support the needs of scientists. The platform is exposed to developers so that they can easily upload their own analysis services into the system and make these available to other users. A representational state transfer-based application programming interface (API) is also provided so that external applications can leverage the platform's functionality, making it easier to build scalable, secure cloud-based applications. This paper describes the design of e-SC, its API and its use in three different case studies: spectral data visualization, medical data capture and analysis, and chemical property prediction.
