Server Clustering and Load Balancing

Server Clustering is the configuration of multiple computer servers into a cluster, which is a group of servers that acts like a single system. 

A server cluster is usually connected to the network through a device called a Load Balancer, which is a single point of access to the cluster. 

The Load Balancer receives requests from the network and distributes the workload across the machines in the cluster to minimize response times and maximize efficiency.
