CAREER: CCF-SHF Advanced Execution Environments for Next-generation Cloud Applications

未来几年，传统的桌面或服务器应用程序将转变为一种由以下几种趋势共同主导的模式：基于Web的应用程序交付、实用程序计算、软件即服务、数据混搭以及Web定制的客户端扩展。这种向下一代云应用的范式转变深刻地改变了用户使用万维网的方式，并为加速科学发现提供了巨大的潜力。这一转变的一个关键组件是提供复杂应用程序的Web浏览器和服务器基础设施，这些复杂应用程序通常由来自不同来源的多个相互连接的组件组成。该研究旨在创建高级浏览器和服务器执行环境，以满足这些应用程序的需求。该项目整合了一个研究和教育计划，该计划开发高级执行环境的抽象，可以有力地支持下一代云应用程序。我们主要关注一种称为脚本空间的高级客户端执行环境。脚本空间提供了一个能够以可靠、健壮、安全、灵活和可扩展的方式支持云应用程序客户端的环境。补充性工作提供了一个服务器端执行环境。我们正在制作抽象的原型，并通过将它们应用于日常使用的客户端混搭框架来验证我们的技术。我们的教育计划应用我们创造的研究成果，通过在学生作业中强调真实世界的背景来重振我们的本科课程，即使在第一门CS课程中也是如此。

The next years will see a shift from traditional desktop or server applications to a model that is dominated by the confluence of several trends: web-based application delivery, utility computing, software as a service, data mash-ups, and client-side extensions for web customization. This paradigm shift to next-generation cloud applications profoundly changes the way in which users use the world wide web and provides tremendous potential for accelerating scientific discovery. A crucial component in this shift is the web browser and the server infrastructure delivering those complex applications, which typically consist of multiple, interconnected components from different sources.This research aims to create advanced browser and server execution environments that address the needs of these applications.This project integrates a research and education plan that develops abstractions for advanced execution environments that can robustly support next-generation cloud applications. Our primary focus falls on an advanced client-side execution environment called script spaces.Script spaces provide an environment that can support the client side of cloud applications in a reliable, robust, secure, flexible, and scalable fashion. A complementary effort provides a server-side execution environment. We are prototyping our abstractions and validate our techniques by applying them to a client-side mash-up framework that is in daily use. Our education plan applies the research artifacts we create to reinvigorate our undergraduate curriculum by emphasizing real-world contexts in student assignments, even in a first CS course.
