A real server is a server that is bound to the created CLB instance to process requests forwarded by the CLB instance. When configuring a CLB listener, you need to bind real servers to the listener. Through different polling methods, the CLB instance forwards requests to the real server for processing to ensure application stability and reliability. Supported Real Server Types
Real servers of the IP type mainly refer to the private IP addresses of VPCs and IDCs.
Reminders
When adding a real server, you are advised to do the following:
Enable session persistence, so that CLB can maintain a longer TCP connection for reuse by multiple requests, thereby reducing load on the web server and improving CLB throughput. Make sure that the security group of the real server has inbound rules for CLB listener ports and health check ports. For more information, see Configuring CVM Security Groups. References
