Detailed explanation-1: -In the distributed system, data is duplicated mainly for “reliability” and “performance”. Replication is required, especially if the distributed system needs to grow in quantity and geographically. Replication is such one of the scaling techniques.
Detailed explanation-2: -Replication in computing involves sharing information so as to ensure consistency between redundant resources, such as software or hardware components, to improve reliability, fault-tolerance, or accessibility.
Detailed explanation-3: -Distributed Database Replication is the process of creating and maintaining multiple copies (redundancy) of data in different sites. The main benefit it brings to the table is that duplication of data ensures faster retrieval.
