Database Clustering
Database clustering is a technique that involves grouping multiple database servers together to work as a single system, providing high availability, scalability, and fault tolerance. It distributes data and workload across nodes to improve performance and ensure continuous operation even if some nodes fail. This approach is commonly used in mission-critical applications where downtime is unacceptable.
Developers should learn database clustering when building systems that require high reliability, such as e-commerce platforms, financial services, or real-time applications, to prevent data loss and service interruptions. It is essential for scaling read/write operations and handling large volumes of concurrent users, making it a key skill for distributed systems and cloud-based architectures.
