Section titled “Concept”Amazon Route 53 is AWS’s DNS service, which finds the real server address from a website’s name. It has three main jobs: registering domain names, DNS routing, and health checking. All the DNS records for a domain are kept in a hosted zone. With a routing policy you can decide which server to send users to, such as the closest or a healthy one. Route 53 connects easily with CloudFront, Elastic Load Balancing and S3.
