We have an application hosted on AWS backed by Application load balancer.
subdomain.example.com and domain
example.com is managed by an external registrar and they have their NS records we they cannot change. They could setup a CNAME record pointing to alias
prod.internaldomain.com which is managed by AWS route 53 and routes the request to AWS Application load balancer (ALB)
prod.elb-xyz.eu-west-1.elb.amazonaws.com DNS which is generated dynamically and does not have an IP address.
my question is, if we install the SSL cert
subdomain.example.com on AWS ALB
prod.elb-xyz.eu-west-1.elb.amazonaws.com would it work? or is there any other way?
