The massive growth of connected devices, including sensors and machines, is revolutionizing every aspect of human life. The socioeconomic impacts are significant and have already transformed many industries. In this article, we discuss some of the challenges of the explosion of devices and exponential growth in personal digital content and machine generated data. The centralized cloud architecture adopted in the early days of mobile Internet was designed primarily to allow access to data stored on the worldwide web. Today, use cases have evolved significantly. Humans and devices are now producing most of the data consumed on the Internet. As a result, the existing centralized cloud infrastructure is no longer efficient or sustainable. There is significant waste of network bandwidth to send terabytes of data to server farms that may be hundreds of kilometers away from the source and/or destination of data. The prevalent centralized cloud architecture does not adequately leverage massive amounts of computing resources on smart devices, which are idle most of the time. Moreover, despite all the efforts to reduce network latencies, communication to server farms is a major bottleneck for latency in many applications. We introduce a novel architectural approach to cloud decentralization called hybrid edge cloud (HEC) that minimizes network bandwidth usage, reduces communication latencies, and leverages resources on smart devices to reduce the burden on server farms and other centralized computing resources. HEC combines the benefits of new network technologies such as 5G and WiFi 6 in private and public clouds to leverage computing resources on smart devices to build a sustainable decentralized infrastructure for the hyper-connected world.

混合边缘云：分散式云计算的实用方法


包括传感器和机器在内的互联设备的大规模增长正在彻底改变人类生活的各个方面。社会经济影响是巨大的，并且已经改变了许多行业。在本文中，我们讨论了设备爆炸式增长以及个人数字内容和机器生成数据呈指数增长所带来的一些挑战。移动互联网早期采用的集中式云架构主要是为了访问存储在万维网上的数据而设计的。如今，用例已经发生了显着的发展。现在，人类和设备正在生成互联网上消耗的大部分数据。因此，现有的集中式云基础设施不再高效或可持续。将数 TB 的数据发送到距离数据源和/或目的地可能数百公里的服务器场会严重浪费网络带宽。流行的集中式云架构无法充分利用智能设备上的大量计算资源，而智能设备大部分时间都处于闲置状态。此外，尽管尽一切努力减少网络延迟，但与服务器场的通信仍然是许多应用程序中延迟的主要瓶颈。我们引入了一种新颖的云去中心化架构方法，称为混合边缘云（HEC），它可以最大限度地减少网络带宽的使用，减少通信延迟，并利用智能设备上的资源来减轻服务器群和其他集中式计算资源的负担。 HEC结合了私有云和公共云中的5G和WiFi 6等新型网络技术的优势，利用智能设备上的计算资源，为超连接世界构建可持续的去中心化基础设施。
