Fault-tolerant fault tolerance for component-based automation systems

To guarantee high availability, automation systems must be fault-tolerant. To this end, they must provide redundant solutions for the critical parts of the system. Classical fault tolerance patterns such as standby or N-modular redundancy provide system stability in the case of a fault. Fault tolerance is subsequently degraded or, depending on the number of deployed replicas, often even unavailable until the system has been repaired.
