Your network routing infrastructure should ensure that all network traffic destined for the backend servers is directed to the FortiADC appliance. Usually, clients access backend servers from the Internet through a firewall such as a FortiGate, so the FortiADC appliance should be installed between your servers and the firewall.

Figure 1 shows a basic deployment. The deployment topology might be different for global load balancing (GLB) or high availability (HA) clusters. Refer to the chapters for those features for illustrations.
