Application Management in Fog Computing Environments: A Taxonomy, Review and Future Directions

Redowan Mahmud, Kotagiri Ramamohanarao, Rajkumar Buyya

摘要:

物联网(IoT)模式正在迅速被用于在各个领域创建智能环境。与智慧城市、医疗保健、工业4.0和Agtech相关的物联网网络物理系统(CPS)处理大量数据,并需要来自不同类型应用程序的实时数据处理服务。物联网应用程序的以云为中心的执行几乎无法满足这些要求,因为云计算中心与物联网设备之间存在多跳距离。\textit{Fog computing}是云在边缘网络上的扩展,可以在更靠近数据源的地方执行这些应用程序。因此,雾计算可以提高应用服务的交付时间,抵抗网络拥塞。然而,雾节点是高度分布,异构和大多数的资源和空间共享的限制。因此,有效管理应用程序是充分利用雾节点功能的必要条件。在这项工作中,我们调查了雾计算中现有的应用程序管理策略,并在架构,放置和维护方面对其进行了审查。此外,我们提出了一个全面的分类,并强调了基于雾的应用程序管理的研究差距。我们还讨论了一个前景模型,并提供了未来的研究方向,进一步改善雾计算中的应用程序管理。

英文摘要:

The Internet of Things (IoT) paradigm is being rapidly adopted for the creation of smart environments in various domains. The IoT-enabled Cyber-Physical Systems (CPSs) associated with smart city, healthcare, Industry 4.0 and Agtech handle a huge volume of data and require data processing services from different types of applications in real-time. The Cloud-centric execution of IoT applications barely meets such requirements as the Cloud datacentres reside at a multi-hop distance from the IoT devices. \textit{Fog computing}, an extension of Cloud at the edge network, can execute these applications closer to data sources. Thus, Fog computing can improve application service delivery time and resist network congestion. However, the Fog nodes are highly distributed, heterogeneous and most of them are constrained in resources and spatial sharing. Therefore, efficient management of applications is necessary to fully exploit the capabilities of Fog nodes. In this work, we investigate the existing application management strategies in Fog computing and review them in terms of architecture, placement and maintenance. Additionally, we propose a comprehensive taxonomy and highlight the research gaps in Fog-based application management. We also discuss a perspective model and provide future research directions for further improvement of application management in Fog computing.
