Connecting the cloud to the factory floor, specifically to industrial control systems (ICS), has been one of those taboo topics for many plant managers. The problem is twofold. First, it’s a cybersecurity risk. Second, control programs require sub-second responsiveness, which shouldn’t—and really can’t—be performed from the cloud.

“It’s a safety concern,” notes Josh Eastburn, director of technical marketing at Opto 22. “We need systems to be responsive in case things trend in the wrong direction. So people are right to be skeptical about moving certain applications to the cloud. It can be done. The question is, should it be done?”
