Architecture of complex, high-speed, Real-Time Instrumentation, Acquisition, Control and Protection systems are typically centralized with a single computer. Data from sensors is acquired, signals processed and actuated upon by a single computer with various Input and Output functionality contained within. As the size of the system grows, or the complexity of the sensors and their data increases, this single computer must be scaled accordingly. This complicates hardware selection and software development and ensuing testing and tuning. Critical sensors that require fail-safe redundancy adds another level of complexity and cost to hardware and software.
