This article focuses on Database Replication, explaining how it ensures high availability, scalability, and disaster recovery in a database system. It begins by highlighting the risk of relying on a single database and introduces replication as a solution that involves copying data from one database to one or more replicas on separate servers.
Replication follows a master-slave model where the master database handles write operations, and the slaves handle read operations. In case of master failure, a slave is promoted to the new master. The article also explores other replication types, such as Multi-Master, Master-Master (Peer-to-Peer), and One-Way Replication.
The advantages of replication include high availability, improved scalability, lower latency, and disaster recovery. However, disadvantages include complexity, consistency issues, performance impacts, costs, and security risks.
