If I have 3 separate websites which all require SSL (separate certificates) that I want to host on the same EC2 instance(s) across multiple availability zones so that we have the ability to scale and be highly available, how do I achieve this using ELBs in my Amazon VPC?
Each site requires a separate IP address, so I have added multiple private IPs to the EC2 instance, but I am unsure how to bind the ELB to a certain IP on the instance.
I was also able to setup multiple ELB pointing to the same instance, but again, I am not seeing any way to bind each ELB to a separate IP on the instance.
If this is not possible, what is the best option?
- Run each site on a separate EC2 instance / ELB combo (expensive and harder to maintain)
- Give each site a separate public IP and use Route 53 to do the load balancing (seems like a hack)
- Use a different load balancer option such as HAProxy that should be able to work like a normal load balancer appliance.
Please help!

I ended up going with a multi domain SSL cert.
