The industrial Internet of Things (IIoT) refers to the use of internet-connected sensors and devices in the industrial sectors, such as manufacturing, energy, automotive, healthcare, life sciences, and agriculture. IIoT allows telemetry data collection from equipment, machines, and field devices in an operational environment. These environments are commonly subject to industrial regulations; compute, networking, and power constraints; and inclement conditions, and all of these challenges contribute to the complexity of designing an IIoT solution.

You can use IIoT data and other enterprise, IT, and operation technology (OT) data to create additional business value, such as optimizing operations, improving productivity, and increasing availability. According to The age of analytics: Competing in a data-driven world (McKinsey Global Institute study), manufacturers can use IIoT data to reduce product development costs by up to 50%, reduce operating costs by up to 25%, and increase gross margins by up to 33%. Therefore, many organizations in the industrial sectors are starting their digital transformation journey to solve business problems by using IIoT.
