Internet of Things (IoT) applications can play a critical role in business and industry. Industrial IoT (IIoT) refers to the use of IoT technologies in manufacturing. Enabling IIoT applications in cloud environments requires the design of appropriate IIoT Platform as-a-Service (IIoT PaaS) to support and ease their provisioning (i.e., development, deployment and management). This paper critically reviews the IIoT PaaS architectures proposed so far in the relevant literature. It only surveys the architectures that are suitable for IIoT applications provisioning and it excludes regular IoT solutions from its scope. The evaluation is based on a set of well-defined architectural requirements. It also introduces and discusses the future challenges and the research directions. The critical review discusses the PaaS solutions that focus on the whole spectrum of IoT verticals and also the ones dealing with specific IoT verticals. Existing limitations are identified and hints are provided on how to tackle them. As critical research directions, the mechanisms that enable the secure provisioning, and IIoT PaaS interaction with virtualized IoT Infrastructure as-a-Service (IaaS) and fog computing layer are discussed.
物联网（IoT）应用在商业和工业中可以发挥关键作用。工业物联网（IIoT）是指在制造业中使用物联网技术。在云环境中启用工业物联网应用需要设计适当的工业物联网平台即服务（IIoT PaaS），以支持并简化其供应（即开发、部署和管理）。本文对相关文献中迄今提出的工业物联网PaaS架构进行了批判性综述。它只调研适用于工业物联网应用供应的架构，并且将常规物联网解决方案排除在其范围之外。评估基于一组明确的架构要求。它还介绍并讨论了未来的挑战和研究方向。该批判性综述讨论了专注于物联网全领域的PaaS解决方案以及处理特定物联网领域的解决方案。识别出了现有局限性，并就如何解决这些局限性给出了提示。作为关键研究方向，讨论了实现安全供应以及工业物联网PaaS与虚拟化物联网基础设施即服务（IaaS）和雾计算层交互的机制。
