I'm trying to wrap my head around DNS and records. Let's say I have a root AWS account with a Route53 Hosted Zone with a domain of example.com, now I want to route beta.example.com traffic to another Route53 HostedZone in another account (that Route53 would then direct traffic to an EC2 instance or ELB), would I create a new CNAME record in my root account? I assume then I would create an alias record in my other account that would direct traffic to my ELB/EC2 (Q1)?
So basically something like this:
root-domain.com CNAME subdomain.root-domain.com
subdomain.root-domain ALIAS ELB/EC2
Why does AWS create 4 NS records (something like ns-1xxx.awsdns.co.uk, ns-1xxxx.awsdns.org) and 1 SOA record? (Q2)
I'm just trying to wrap my head around how all these records work in conjunction with each other (Q3)
Is it possible for me to create a CNAME record that points to www.google.ca? Are CNAME records only for subdomains? (Q4)
