The following describes the differences between Server Load balancer, clusters, and master-slave databases.

1. Server Load balancer: distributes client requests to different normal servers through the Server Load balancer algorithm to reduce the pressure on a single server.

2. Cluster: a cluster is mainly used to solve single point of failure (spof) and prevent another server from providing services when it fails, under normal circumstances, only one server in the cluster works normally.

3. Master/Slave: The Master/Slave server synchronizes data. Normally, the Master/Slave server works normally.
