What is a Server Cluster? (Simple Explanation + How It Works)
A server cluster is a group of multiple servers that work together as a single system to improve performance, reliability, and scalability.
Instead of depending on one machine, workloads are distributed across multiple servers. This means better uptime, faster response times, and fewer chances of downtime if one server fails.
Server clusters are widely used in modern cloud computing, web hosting, and enterprise applications where high availability and performance are critical.
This article breaks down how server clusters work, their key components like load balancing and failover, and why they’re essential for scalable infrastructure.
