Operational technology (OT) and information technology (IT) used to be separate for decades as there was simply no reason to integrate these two areas. Stable OT systems were basically left untouched during the lifetime of a production plant, while IT has always had a reputation for needing frequent changes and being vulnerable to cyber security issues. Nowadays, the concepts of digitalization, Industry 4.0, and IIoT (industrial IoT) make the convergence of IT and OT mandatory in order to optimize business models and production agility.
