Fundamentally speaking, IT pertains to information production and flow, while OT pertains to machines, devices and systems. As per our definition, IT / OT convergence is management of information flow between OT ( machines, devices and systems) and Information Technology (IT), so as to ensure optimal (secure, seamless, low latency, timely, well coordinated, less power / energy consumption) functioning of enterprise / industrial systems. And, because IoT bridges the IT and OT world, IT / OT convergence is a precursor and a lifeline for IoT project’s successful implementation.
