摘要

物联网系统通常利用云来处理和共享收集到的数据,而在边缘进行预处理可以减少传输到网络并在云中处理的数据量。尽管使用集中式和多路复用的高性能资源具有相关优势,但由于短暂的网络故障,边缘云交互可能无法实现,从而对业务连续性产生负面影响。在本文中,我们扩展了边缘计算的采用,通过一个框架,一些云部署的业务逻辑组件和物联网应用的相关数据在Edge中无缝镜像,以提高瞬时网络故障阻碍边缘云通信时的服务可用性。特别是,为了解决由于边缘节点和云之间的数据复制而导致的潜在不一致,我们提出了一种新的分布式一致性算法,称为edgecloudpaxos。它基于分布式的事件驱动技术,在发生分布式本地事务时实现协调。本文介绍了该框架,采用该框架包装现有的用于物品跟踪的应用程序,并通过模拟许多零售商店产生的跟踪活动进行了几次测试,验证了该框架在确保业务连续性和即使在网络故障的情况下也能降低响应时间方面的有效性。

Business continuity of Cloud-based IoT applications through a seamless continuum
IoT systems often exploit the Cloud to process and share collected data, while pre-processing at the Edge reduces the amount of data transferred to the network and processed in the Cloud. Despite the relevant advantages of using centralized and multiplexed high-performance resources, Edge-Cloud interactions might not be possible due to transient network failures, so negatively impacting business continuity. In this paper, we extend the adoption of Edge computing by seamlessly mirroring in Edge, through a framework, some Cloud-deployed components of the business logic and related data of IoT applications to improve service availability when transient network failures impede Edge-Cloud communication. In particular, to address potential inconsistency due to data replication among Edge nodes and Cloud, we propose a new distributed consistency algorithm, called EdgeCloudWPaxos. It is based on a distributed, event-driven technique that implements reconciliation when distributed local transactions occur. The paper presents the framework, its adoption for wrapping an existing application for item tracking, and the validation through several tests conducted by emulating the tracking activity produced by a number of retail shops, which shows the effectiveness of the framework in ensuring business continuity and lower response times even in the case of network failure.
