How it works...
In this recipe, we created a certificate using ACM. We can request a certificate for one or more domain names. We need to specify a fully qualified domain name such as www.heartin.cloud or one that uses a wildcard, such as *.heartin.cloud, that represents all the subdomains of heartin.cloud.
Before issuing the certificate, we need to validate the ownership of the domain. We can do this either through DNS validation or through email validation. We performed DNS validation in this recipe. AWS will provide a CNAME record per domain for DNS validation. We need to update this CNAME record on our domain's DNS management service. Route 53 is Amazon's DNS management service.
