The regular setup I know of is a load balancer terminating SSL and then making unencrypted requests to the backend servers.
If I want to have an SSL connection from the load balancer to the backend servers, though, how do I implement that?
The straightforward thing I can think of is having a separate SSL certificate for each backend server, e.g. https://node1.example.com, https://node2.example.com, https://node3.example.com etc that the load balancer connects to.
Is there a better approach to avoid setting up an individual certificate for each backend server?
