Distributed Systems System Design Interview
Redundancy and replication are two important concepts in system design. Redundancy is the duplication of critical components or functions of a system with the intention of increasing the reliability of the system. Replication is the duplication of data or other resources in order to increase availability and fault tolerance.
Redundancy is used to increase the reliability of a system by providing a backup system in case of failure. This can be done by having multiple copies of the same system or by having multiple systems that can take over in case of failure. Redundancy can also be used to increase the performance of a system by allowing multiple requests to be processed in parallel.
Replication is used to increase the availability and fault tolerance of a system by having multiple copies of the same data or other resources. This can be done by having multiple copies of the same data stored in different locations or by having multiple copies of the same data stored on different servers. Replication can also be used to increase the performance of a system by allowing multiple requests to be processed in parallel.
Both redundancy and replication are important concepts in system design and can be used to increase the reliability, availability, and performance of a system.
