Redundancy, Replication, and Availability Clustering

Redundancy

Redundancy in software architecture refers to the implementation of multiple copies of a component or process in order to increase the reliability and fault tolerance of the system. If one copy of the component or process fails, the other copies can continue to function, allowing the system to continue operating.

There are several ways in which redundancy can be implemented in software architecture, including:

Hardware redundancy

Hardware redundancy involves implementing multiple copies of hardware components, such as servers, storage devices, and networking equipment. If one hardware component fails, the other components can continue to function, ensuring that the system remains available to users.

Data redundancy

Data redundancy involves maintaining multiple copies of data in order to increase the reliability and fault tolerance of the system. If one copy of the data becomes unavailable or corrupted, the other copies can be used to restore the data and keep the system functioning.

Network redundancy

Network redundancy involves implementing multiple copies of networking components, such as ...
