The following figure uses a single LB instance as an example to illustrate the supported load balancing traffic modes. In the figure, "RS" represents the backend server, and "Client" represents the client.
The current architecture contains three network scenarios:
VLAN network scenario: Both client communication and server pool communication use a VLAN network.
VPC north-south scenario: Client communication uses a VLAN network, and server pool communication uses a VPC subnet. This is used for traffic forwarding between VLAN networks and VPC networks.
VPC east-west scenario: Both client communication and server pool communication use a VPC subnet. This is used for traffic forwarding within a VPC.
