Server load balancing configuration example
Network requirements
As shown in Figure 131, three servers Server A, Server B, and Server C can provide HTTP services. Server
A has the highest hardware configuration, and Server B the second. Enable these three servers to provide
HTTP services together, and all HTTP traffic is required to be filtered by the firewall.
Cluster provides HTTP service. Server load balancing should be applied.
All traffic will pass the firewall: NAT-mode server load balancing (Responses in DR mode do not pass the
firewall).
The performance of the three servers is different and therefore weighted round robin algorithm is
adopted.
