随着计算基础设施向边缘延伸，它将越来越多地提供与大型云数据中心相同的细粒度资源调配机制，而低延迟无线网络技术的进步将使服务提供商能够模糊用于商业计算的本地和远程资源之间的区别。从用户的角度来看，他们的设备将不再具有固定的计算能力，而是看起来具有灵活的计算能力，这取决于他们物理上可用的共享、分解的边缘资源。系统软件将透明地利用这些短暂的资源来提供更好的最终用户体验。我们讨论了实现这种紧密耦合、分散和短暂的基础设施配置的关键系统挑战，倡导在该领域进行更多研究，并概述了可能的前进道路。
As computational infrastructure extends to the edge, it will increasingly offer the same fine-grained resource provisioning mechanisms used in large-scale cloud datacenters, and advances in low-latency, wireless networking technology will allow service providers to blur the distinction between local and remote resources for commodity computing. From the users' perspectives, their devices will no longer have fixed computational power, but rather will appear to have flexible computational capabilities that vary subject to the shared, disaggregated edge resources available in their physical proximity. System software will transparently leverage these ephemeral resources to provide a better end-user experience. We discuss key systems challenges to enabling such tightly-coupled, disaggregated, and ephemeral infrastructure provisioning, advocate for more research in the area, and outline possible paths forward.
