The duplication of critical components or functions of a system to increase its reliability.

Get started

What is Redundancy in cloud computing?

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 can help ensure system availability even in the event of a component failure.
  • It's often used in conjunction with backup and disaster recovery strategies.

How does Redundancy work?

Redundancy works by creating duplicates of critical components or functions of a system.

  • If a component fails, the redundant component takes over to ensure the system continues to operate smoothly.
  • Redundancy can be implemented at various levels, including hardware, software, and data.

Redundancy Example

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.
