Load Balancer
The vShield Edge provides load balancing for HTTP traffic. Load balancing (up to Layer 7) enables Web
application auto‐scaling.
Figure 5-2. vShield Edge Providing Load Balancing Service for Protected Virtual Machines
You map an external (or public) IP address to a set of internal servers for load balancing. The load balancer
accepts HTTP requests on the external IP address and decides which internal server to use. Port 80 is the
default listening port for load balancer service.
All Load Balancer settings configured by using REST requests appear under the vShield Edge > Load Balancer
tab for the appropriate vShield Edge in the vShield Manager user interface and vSphere Client plug‐in.
For the load balancer schema, see "Load Balancer Schema" on page 86.
