Route 53

Route 53 is the DNS service in AWS. It is a global and scalable DNS service that allows you to perform some advanced operations:

• Register domain names
• Transfer domain names from other registrars
• Create traffic routing policies (such as failovers across regions)
• Monitor the availability of your applications (and reroute the traffic to healthy instances).

With Route 53, we can link domain names to AWS resources, such as load balancers, S3 buckets, and other resources, enabling us to expose a human-readable name for our resources (mainly VMs) created within our AWS instance.
