I want set up AWS load balancing on my EC2 instance, but I have a kind of dynamic SSL certificate management on it, and because of that, I need use the server's SSL certificate instead of setting up a certificate on the load balancer. Is this possible?
If you want to terminate SSL/TLS connection on the web servers (and not on the LB(s) ) you can set LB to balance TCP connection and not SSL/TLS. Of cource this have some disadvantages but based on your requirements this seems to be the only way.
BTW if you have only one web server/service it is strange for me you want to balance it. LB is normally applied when you have more than one.
