What is TSL/SSL termination?
TSL/SSL termination is where a full public certificate, along with its private key, is uploaded to the load balancer and associated to a TLS/SSL termination virtual service.
Data is encrypted from the client to the load balancer but is decrypted at the load balancer, becoming plain text HTTP. Performing TLS termination on the load balancer can be very CPU intensive. In most cases, for a scalable solution, terminating TLS on the real servers is the best option.
