An Application Load Balancer (ALB) supports both HTTP and HTTPS listeners. By attaching an ACM-managed SSL/TLS certificate to the HTTPS listener on port 443 and configuring a redirect rule in the HTTP (port 80) listener to forward traffic to HTTPS, the ALB automatically redirects all HTTP requests to HTTPS, meeting both the security and operational requirements.
