bottleneck. By using server load balancing, you can properly distribute network services to
multiple servers for processing. This reduces the burden of a single server, improves the service
processing capabilities, and ensures the high reliability of services. To upgrade the network or
improve the server performance, you simply need to add servers to a server group, without
changing the current network structure and stopping existing services.
