according to certain algorithms, balance the load of all servers in the cluster as much as possible. For external clients, they do not know which server in the cluster is accessed. multiple servers can be regarded as a "large" server logically. In this way, when the service capabilities of the cluster cannot meet the current needs, it is very convenient to add new servers to the cluster to meet the needs. It can be seen that the system has excellent
