SANs per cert and SNI for hosting service

Thanks for the response and the recommendations.

From the original thread:

So I think we are stuck with using SAN certificates at this point in time.

We considered going with the second approach but it would require a separate load balancer for each certificate and DNS changes for everyone on top of the extra maintenance requirements and extra costs of using 3 more load balancers.

Unless you happen to have any other ideas or suggestions?
