Database Replication in System Design | Master-Slave Architecture Explained

In this video, we explain Database Replication and Master-Slave Architecture in System Design with simple examples. Database replication is a technique used to maintain copies of data across multiple database servers. It helps improve read performance, availability, scalability, and fault tolerance. In this video, you will learn: What is Database Replication? Why do we need database replication? What is Master-Slave Architecture? How the master and replica databases communicate How write operations are handled How read requests can be distributed across replicas Synchronous vs Asynchronous Replication How replication helps improve scalability and availability What happens when the master database fails Real-world use cases and limitations We will understand how database replication works through architecture diagrams and practical examples, making this an easy-to-follow introduction to an important System Design concept. This topic is useful for anyone learning backend development, distributed systems, database design, and system design interview preparation. Note: Master-Slave Architecture is also commonly referred to as Primary-Replica Architecture.
