Software-Defined Automation Shatters the Factory's Hardware Monolith

Virtual PLCs and Industrial Edge computing bring software development practices to the factory floor, enabling rapid iteration, testing, and deployment that were impossible in the PLC monolith era. This shift mirrors the DevOps revolution that already reshaped cloud and networking industries, transforming automation from static, hardware-locked systems to dynamic, version-controlled infrastructure. While the expanded attack surface poses new security challenges, the ability to patch and update at software velocity represents a fundamental transformation in how industrial systems can evolve.
