Data Replication
Data replication is the process of copying and distributing data from one database or storage system to another, ensuring consistency across multiple locations. It enables data availability, fault tolerance, and performance optimization by maintaining synchronized copies. This concept is fundamental in distributed systems, cloud computing, and disaster recovery scenarios.
Developers should learn data replication to build scalable, resilient applications that require high availability and low-latency access to data, such as in e-commerce platforms or global services. It's essential for implementing disaster recovery plans, load balancing across servers, and supporting real-time analytics in distributed environments like microservices architectures.
