I am setting up a server on EC2 that will be used by people that will be freaked out when they see ec2-111-111-111-111.compute-1.amazonaws.com in the URL bar. I know this would be solved by using an A record rather than a CNAME, yet Amazon's documentation says to use a CNAME.
What happens if I use an A record? I've seen some tutorials on the web saying do it, but I also need my website to be reliable.
The website is just running using one instance, and will probably only run using one instance, so I don't think it matters to have multiple instances talk to each other.
