The digital transformation trend currently dominates the entire industrial world. Modern factories, energy power plants, manufacturing facilities and warehouses are becoming “smarter” with the help of Industrial Internet of Things (IIoT) and Edge computing, processing and analyzing in real-time huge quantities of data to increase operational efficiency, reduce production downtime and costs. Industrial Internet of Things (IIoT) is becoming more important, especially considering real time processing needed in industrial sector.
As such traditional cloud solutions alone seem not to cover all requirements where each second can count to make instant decisions.
In this context, Edge computing proves crucial, processing data closer to devices and machines, without depending of cloud communication. In this guide we shall cover Industrial IoT and Edge Computing, their usage together, use cases, predictions on preventive maintenance, and edge solutions used in Industry 4.0.
