Does each server (EC2 Node) behind a load balancer need their own SSL certificate?

Question

I have 2 EC2 nodes behind a load balancer. I need to setup SSL certificate for use with Amazon Web Services. Does each server behind a load balancer need their own SSL certificate? Or only the load balancer need the SSL certificate?

Answer 1

You can associate the SSL certificate with the load balancer, and then use either normal HTTP between the Load Balancer and the server, or another form of authentication that is less resource-intensive than SSL.
