On AWS, I'm hosting Multiple (totally different) Domains on EC2 covered by an ELB on top. I already have 1 Wildcard SSL Cert for 1 Domain and its childs. (xxxx.site1.com)
Then now can I add one more Single SSL Cert (on same ELB) for 1 another different Domain, like (www.site2.com) please?
I'm asking this because some Articles are saying, it won't work and just crush.
Please kindly advise.
No. The only way you could do it is if you use a second port for HTTPS connections (other than 443) which doesn't apply to real world scenarios since 443 is the default port for HTTPS
Having said that, you can simply create a second ELB and assign your second wildcard certificate to it. You can also forward your traffic to the same backend server as the one where the first ELB is forwarding its traffic to.
Hope this helps.
