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