Redundancy plays a critical role in architectural resilience by providing a backup system or component that can take over in case of failure or disruption of the primary system or component. Redundancy can be achieved through various means, such as duplicating critical systems, implementing backup power supplies, or having multiple communication channels. By having redundancy in place, the system can continue to function even if some components or subsystems fail, minimizing downtime and maintaining the system's performance and reliability. This approach enhances the system's resilience and reduces the impact of potential threats or disasters.
