Ssl – How to set Load Balancers onto EC2 (installed Apache with SSL)

AWS Elastic Load Balancer supports SSL termination at the load balancer. This means you can install your SSL certificate on the load balancer itself. The load balancer will then talk unencrypted HTTP between the load balancer and your EC2 instance.

This way you only have to install the certificate on the ELB instead of every machine. Have your Apache/Nginx/Lighttpd/whatever use plain HTTP, not SSL. Let the load balancer handle all of the SSL.

The private key is mydomain.key which you generated along with the CSR.

What GoDaddy has sent you is the public key (the certificate file mydomain.com.crt, as signed by GoDaddy), as well as the intermediate certificate chain for GoDaddy that complete the chain of trust between your certificate and what an end-user's browser knows about (the gd_bundle.crt file).

I'm not specifically familiar with ELB, but looking at this documentation page:

http://docs.amazonwebservices.com/ElasticLoadBalancing/latest/DeveloperGuide/US_UpdatingLoadBalancerSSL.html

You will supply your mydomain.key file for the private key, the mydomain.com.crt file for the public key, and the gd_bundle.crt file for the certificate chain.
