Widespread deployment of centralized clouds has changed the way internet services are developed, deployed and operated. Centralized clouds have substantially extended the market opportunities for online services, enabled new entities to create and operate internet-scale services, and changed the way traditional companies run their operations. However, there are types of services that are unsuitable for today's centralized clouds such as highly interactive virtual and augmented reality (VR/AR) applications, high-resolution gaming, virtualized RAN, mass IoT data processing and industrial robot control. They can be broadly categorized as either latency-sensitive network functions, latency-sensitive applications, and/or high-bandwidth services. What these basic functions have in common is the need for a more distributed cloud infrastructure—an infrastructure we call edge clouds. In this paper, we examine the evolution of clouds, and edge clouds especially, and look at the developing market for edge clouds and what developments are required in networking, hardware and software to support them.

未来边缘云

集中式云的广泛部署改变了互联网服务的开发、部署和运营方式。集中式云极大地扩展了在线服务的市场机会，使新实体能够创建和运营互联网规模的服务，并改变传统公司的运营方式。但是，有些类型的服务不适合当今的集中式云，例如高度交互的虚拟和增强现实 (VR/AR) 应用程序、高分辨率游戏、虚拟化 RAN、海量物联网数据处理和工业机器人控制。它们可以大致分为延迟敏感的网络功能、延迟敏感的应用程序和/或高带宽服务。这些基本功能的共同点是需要更加分布式的云基础设施——我们称之为边缘云的基础设施。在本文中，我们研究了云的演变，尤其是边缘云的演变，并着眼于边缘云的发展中市场以及网络、硬件和软件需要哪些发展来支持它们。
