A load balancer can work on either a public or private network.
You can bind an EIP to a load balancer so that it can receive requests from clients on the Internet and route the requests to backend servers.
Figure 1 Load balancing on a public networkA load balancer has only a private IP address to receive requests from clients in a VPC and route the requests to backend servers in the same VPC. This type of load balancer can only be accessed in a VPC.
