Foundations of the Industrial Internet of Things (IIoT)

The industrial world is undergoing a massive digital transformation as physical machinery connects to cloud networks. Understanding how these complex systems communicate is essential for anyone looking to work in modern manufacturing, logistics, or infrastructure. This course guides you from a beginner level to a solid understanding of how industrial devices interact with humans, other machines, and the cloud. You will learn to analyze IIoT architectures and identify opportunities for automation and predictive maintenance. In this course, you will: Understand the foundational architecture of the Industrial Internet of Things (IIoT) and how it differs from consumer IoT; Analyze device-to-device (D2D) and device-to-cloud communication protocols like MQTT and CoAP; Explore basic data flows from industrial sensors to edge computing nodes for real-time processing; Evaluate security challenges in industrial networks and apply zero-trust security concepts to protect critical assets; Identify predictive maintenance opportunities and modern data analysis patterns within industrial workflows. The course starts with essential terminology, basic network architectures, and historical context before guiding you through communication protocols, edge computing, and cybersecurity best practices. You will read through practical scenarios and analyze real-world case studies to solidify your understanding. This course is designed for beginners, aspiring automation professionals, or tech enthusiasts with no prior experience in industrial networks.
