A web-hosting startup manages more than 500 public web applications on AWS Cloud which are deployed in a single AWS Region. The fully qualified domain names (FQDNs) of all of the applications are configured to use HTTPS and are served via Application Load Balancers (ALBs). These ALBs are configured to use public SSL/TLS certificates. The startup has hired you as an AWS Certified Solutions Architect Professional to migrate the web applications to a multi-Region architecture. You must ensure that all HTTPS services continue to work without interruption. Which of the following solutions would you suggest to address these requirements?
