Description
"Redundancy is the duplication of critical components or functions of a system with the intention of increasing reliability of the system, usually in the form of a backup or fail-safe, or to improve actual system performance." - Redundancy (engineering), Wikipedia
Redundancy in engineering is a key practice to ensure that systems remain operational in the event of component failures. It involves creating multiple instances of critical components so that if one fails, the others can take over seamlessly. This practice is essential in systems where reliability and availability are critical, such as in data centers, aerospace, and power systems. Implementing redundancy helps in maintaining service quality and availability, thereby reducing the risk of operational disruptions.
