server group. The load balancing group provides HTTP services through a virtual IP address.
The user IP address is 10.10.10.2, the virtual IP address is 20.20.20.2:80, and the IP addresses
of the four servers are 192.168.20.1:80, 192.168.20.2:4002, 192.168.20.3:80, and
192.168.20.4:8080. The processing capabilities of each server such as the CPU, memory, and
