Replication is the process of maintaining multiple copies of data across different nodes or servers in a distributed system. The primary goals are to improve availability, fault tolerance, and performance by ensuring that if one node fails, the data remains accessible from other nodes.
Key benefits include:
High Availability: System remains operational even if some nodes fail
Fault Tolerance: Data is preserved even during hardware failures
Performance: Reduced latency by serving data from geographically closer replicas
Load Distribution: Multiple nodes can handle read requests simultaneously
