Workshop titled "Toward a Research Agenda for Cloud 3.0"

该奖项资助了一个重点研讨会，其目标是将网络系统的主要研究人员和实践者聚集在一起，为“云3.0”制定新的网络研究议程，重点是重新思考数据中心内外的网络系统基础设施。背景：近年来，我们见证了IT行业的两次巨大变革。首先，虚拟化和私有数据中心使组织能够以更灵活和更具成本效益的方式使用有限的计算资源。其次，云计算和公共云使组织能够外包其IT基础设施，从而大大降低了资本和运营费用。我们现在正准备迎接第三个巨大的转变：“无服务器”平台，或“云3.0”，它有可能重塑硬件和软件架构。在Cloud 3.0中，应用程序开发人员只需提供代码和数据，而无需担心基础设施（例如，配置和旋转云资源）。应用程序开发人员甚至将最复杂的应用程序定义为一组简单的无状态函数（lambda）。基础设施提供商（例如，公共云运营商）处理所有复杂的“细节”（例如，获取资源、管理故障、确保良好的用户体验等）。这种模式提供了许多好处，包括以更快的速度开发创新应用程序、快速适应用户需求、提高成本效益等。几家大型在线服务提供商已经开始提供无服务器计算平台，并将其吹捧为“云的未来”。当前支持此类Cloud 3.0应用程序、基础设施和网络的方法是重新利用现有的硬件和软件、协议和算法。但是有几个地方，特别是在云网络方面，现有的技术不太适合云3.0。例如，在硬件层面，最近对分解网络设计的研究也有可能进一步侵蚀定义服务器的硬边界。类似地，重新思考网络协议、抽象、应用程序编程接口（api）和算法的新方法可能导致对无服务器计算的更优支持。“云3.0”为有趣的核心网络以及跨领域（“网络+ X”）研究提供了丰富的机会。可能在研讨会上探讨的感兴趣的主题包括：新的数据中心架构和网络互连；lambda和分解网络架构之间的协同作用；路由和链路层协议支持lambda ？性能、扩展、隔离；可编程结构和控制平面，可以支持Lambdas所需的敏捷性；重新审视传输和网络层协议设计；重新审视旧的抽象，如套接字A；Lambda隔离、安全性和记帐，以及必要的网络支持。首席研究员将与研讨会参与者一起撰写一份详细的研讨会报告，该报告将概述云3.0的网络研究议程。该报告将在公共讲习班网站上发布。该网站还将包括参与者名单、他们的传记以及他们在研讨会前的一页报告。

This award funds a focused workshop with the goal of bringing together leading researchers and practitioners in networked systems to develop a new networking research agenda for "Cloud 3.0", focusing on rethinking from the ground-up networked systems infrastructure within the datacenter and beyond. Background: In recent years we have witnessed two dramatic transformations of the IT industry. First, virtualization, and private data centers, enabled organizations to use limited compute resources in a more flexible and cost-effective fashion. Second, cloud computing, and public clouds, enabled organizations to outsource their IT infrastructure, vastly reducing capital and operational expenses. We are now poised for the third dramatic shift: "serverless" platforms, or "Cloud 3.0", which has the potential to reinvent both hardware and software architectures. With Cloud 3.0, application developers just bring code and data without worrying at all about the infrastructure (e.g., configuring and spinning up cloud resources). Application developers define even the most complex applications as a set of simple stateless functions, or lambdas. An infrastructure provider (e.g., a public cloud operator) handles all the complex "details" (e.g., acquiring resources, managing failures, ensure good user experience, etc.). This model offers many benefits including development of innovative applications at much greater speed, rapid adaptation to user demand, improved cost-effectiveness, etc. Several large online service providers have begun offering platforms for serverless computation, touting this as "the future of the Cloud".The current approach to supporting such Cloud 3.0 applications, infrastructure, and networking is to re-purpose existing hardware and software, protocols, and algorithms. But there are several places, especially in cloud networking, where existing technologies are a poor fit for Cloud 3.0. For example, at the hardware level, recent research in disaggregated network designs has the potential to further erode the hard boundaries defining servers as well. Similarly, new approaches to rethinking network protocols, abstractions, application programming interfaces (APIs), and algorithms may lead to more optimal support for serverless computing. "Cloud 3.0" provides a rich set of opportunities for interesting core networking, as well as cross-cutting ("networking + X") research. Topics of interest that are likely to be explored at the workshop include: new datacenter architectures and networking interconnects; synergy between Lambdas and disaggregated network architectures; routing and link layer protocols to support Lambdas? performance, scale up, isolation; programmable fabrics and control planes that can support agility needed by Lambdas; revisiting transport and network layer protocol design; revisiting old abstractions such as the socket A ; Lambda isolation, security, and accounting, and the necessary support at network.The principal investigator, along with workshop participants, will author a detailed workshop report which will outline a networking research agenda for Cloud 3.0. The report will be made available on the public workshop website. The website will also include a list of participants, their biographies, and their one-page pre-workshop write-ups.
