What Is Infrastructure Redundancy?
Quick answer: Redundancy means providing an alternate component, route, supply, or capacity so an essential service is less dependent on a single point of failure.
Where can redundancy help?
Depending on the system, redundancy can involve backup pumps or power, alternate network paths, spare capacity, or operational workarounds. The appropriate level depends on the probability and consequences of failure.
What does resilience research say?
World Bank resilience research emphasizes redundancy as one tool for improving service continuity, alongside maintenance, demand management, and broader network planning.
