Replication
Replication is a fundamental concept in computing and data management that involves creating and maintaining multiple copies of data, services, or systems across different locations or nodes. It ensures high availability, fault tolerance, and improved performance by distributing workloads and providing redundancy. This technique is widely used in databases, distributed systems, and storage solutions to enhance reliability and scalability.
Developers should learn replication to build resilient and scalable applications, especially in distributed environments where downtime or data loss is unacceptable. It is crucial for use cases like disaster recovery, load balancing across multiple servers, and maintaining data consistency in globally distributed systems such as e-commerce platforms or real-time analytics. Understanding replication helps in designing systems that can handle failures gracefully and provide seamless user experiences.
