Final answer:
To configure the corporate website availability on both www.acme.com and acme.com, you should use an ALIAS record for both acme.com and www.acme.com in Amazon Route 53, targeting the Elastic Load Balancer.
Explanation:
To ensure that your organization's corporate website is available on both www.acme.com and acme.com, you need to configure DNS entries in Amazon Route 53 properly. The correct way to set up these DNS records is Configure acme.com with an ALIAS record targeting your Elastic Load Balancer (ELB).Configure www.acme.com with an ALIAS record or a CNAME record that targets acme.com.
If you are using Amazon Route 53 and your ELB supports it, the ALIAS record is AWS-specific and allows you to point your apex domain, which is acme.com without the 'www', directly to the ELB. This is generally preferred as it can help with certain AWS services like Elastic Beanstalk or CloudFront distributions. For the www subdomain, you can use a CNAME record in some scenarios, but using an ALIAS record provides better integration with AWS services, so it's often the recommended approach.This option uses ALIAS records, which are recommended for pointing domain names to AWS resources like the Elastic Load Balancer (ELB). By configuring both acme.com and www.acme.com with ALIAS records targeting the ELB, the website will be available on both domain names.
