Historically, the manufacturing industry has relied on centralized computing architectures, primarily cloud computing, to process the massive volumes of data generated by factory floor sensors, robotics, and supply chain systems. While cloud computing offers unparalleled scalability and storage capacity, it introduces latency and bandwidth constraints that are incompatible with the real time demands of modern manufacturing. The manufacturing industry is undergoing a profound transformation driven by the principles of Industry 4.0, where cyber physical systems, the Internet of things IoT , and artificial intelligence AI converge to create intelligent, self optimizing production environments. At the heart of this digital revolution lies edge computing, a decentralized computing paradigm that processes data at or near the source of generation rather than relying solely on centralized cloud data centers. By placing computational resources such as edge servers, industrial gateways, and smart sensors directly on the factory floor, edge computing enables localized data analysis and immediate action. Edge computing in manufacturing moves computation closer to machines and production lines. This paper explores the critical role of edge computing in modern manufacturing. edge computing, cloud computing, manufacturing, factory. 1-10 Issue-4 Volume-10 Matthew N. O. Sadiku | Samuel A.
