Having only Https setup for the Domain using Route 53 in AWS

Question

We have a Domain set up from route 53.

currently, it is working both with HTTP://domainname and Https://domainname.

We want to have it restricted only to Https. How can we achieve this in AWS?

Answer 1

Since the application load balancer (ALB) is used, http to https redirection should be performed on ALB. The procedure is described in recent AWS blog post:

• How can I redirect HTTP requests to HTTPS using an Application Load Balancer?

It involves setting up HTTP listener which will redirect HTTP requests on port 80 to HTTPS listener on port 443.

To enable this, HTTPS listener must be setup with SSL certificate. The easiest to use would be to get free SSL certificate from AWS Certificate Manager (ACM) as shown in:
