The conventional cloud-centric Internet of Things (IoT) application fails to meet the latency requirement of time-critical applications. The idea of edge and fog computing arrived to distribute workloads across the fog devices located in the local area. However, achieving seamless interoperability, platform independence, and automatic deployment of services becomes the major challenge over heterogeneous fog devices. This paper proposes an integrated and standards-based fog computing federation framework, FogDEFT, that adapts OASIS–Topology and Orchestration Specification for Cloud Applications (TOSCA) for service deployment in fog. The framework standardizes the distributed application design with TOSCA Service Template to deploy Docker Containers in Swarm mode and manages interoperability over heterogeneous fog devices. The framework uses a lightweight TOSCA compliant orchestrator to dynamically deploy various fog applications (user-developed services) on the fly.

开箱即用的雾计算：使用 TOSCA 动态部署雾服务容器

传统的以云为中心的物联网（IoT）应用无法满足时间关键型应用的延迟要求。边缘和雾计算的想法是为了在本地区域的雾设备之间分配工作负载。然而，实现无缝互操作性、平台独立性和服务的自动部署成为异构雾设备的主要挑战。本文提出了一种基于标准的集成雾计算联邦框架 FogDEFT，该框架采用 OASIS – 云应用拓扑和编排规范 (TOSCA) 来进行雾中的服务部署。该框架使用 TOSCA 服务模板标准化分布式应用程序设计，以 Swarm 模式部署 Docker 容器，并管理异构雾设备上的互操作性。
