With a TLS-terminated HTTPS load balancer, web clients communicate with the load balancer over TLS protocols. The load balancer terminates the TLS session and forwards the decrypted requests to the back-end servers. By terminating the TLS session on the load balancer, we offload the CPU-intensive encryption work to the load balancer, and enable the possibility of using advanced load balancer features, like Layer 7 features and header manipulation.

Presently, TLS-terminated HTTPS load balancers are not supported in any released OSP version. This is a much-needed feature required in production environments.
