5.11.3.3. Example: vCloud Networking and Security Edge as a Load balancer
vCloud Network and Security Edge (Edge) offers basic HTTP (80) and HTTPS (443) load balancing. It can be used for applications that only need one or both of these protocols to work. Edge can be used to load balance vCloud Director cells, as well as basic web server configuration.
Figure 37. vCloud Networking and Security Edge as a Load Balancer
Edge currently has limited load balancing advanced features such as SSL termination and stickiness. If advanced features are critical to the operation of the application being load balanced, then a third-party virtual or physical load balancing appliance should be evaluated.
In Figure 37 the edge provides
the load balancing functionality and firewall needed to secure the vApp workloads.
As with the third-party virtual appliance as a load balancer example, the DMZ network should be an isolated vApp or organization virtual datacenter network, but the public network should be a vApp or organization virtual datacenter network that is bridged to the external network that routes to where the clients are located.
