The duplication of critical components or functions of a system to increase its reliability.
In cloud computing, redundancy refers to the duplication of certain components or functions of a system with the intention of increasing its reliability and availability. It's a common strategy used to prevent data loss and downtime in the event of a failure.
Redundancy works by creating duplicates of critical components or functions of a system.
A cloud service provider, CloudServe, might implement redundancy by duplicating critical hardware components, such as servers and hard drives. If a server fails, the redundant server can take over, ensuring that CloudServe's services remain available to its customers.
A characteristic of a system which aims to ensure an agreed level of performance, usually uptime, for a higher than normal period.
