The general idea behind setting up a redirection is to sidestep your domain apex entirely and redirect your users transparently to a subdomain, from which you will be able to create a CNAME to an Aptible Endpoint Hostname.

Most customers often choose to use a subdomain such as www or app for this purpose.

To set up a redirection from your domain apex to a subdomain, we strongly recommend using a combination of AWS S3, AWS CloudFront, and AWS Certificate Manager. Using these three services, you can set up a redirection that is easy to set up and requires absolutely no maintenance going forward.

To make things easier for you, Aptible provides detailed instructions to set this up, including a CloudFormation template that will automate all the heavy lifting for you.
