Managing Public DNS - Web Application Hosting in the AWS Cloud: Best Practices

Managing Public DNS

Moving a web application to the AWS Cloud requires some DNS changes to take advantage of the multiple Availability Zones that AWS provides. To help you manage DNS routing, AWS provides Amazon Route 53, a highly available and scalable DNS web service. Amazon Route 53 automatically routes queries for your domain to the nearest DNS server. As a result, queries are answered with the best possible performance. Amazon Route 53 resolves requests for your domain name (for example, www.example.com) to your Classic Load Balancer, as well as your zone apex record (example.com).
