Route 53 and DNS Basics
Learn how domain name resolution works and how to use Amazon Route 53 for it.
We'll cover the following...
Working with AWS, understanding DNS and how Route 53 handles domain resolution is foundational to building resilient, user-friendly applications. DNS (domain name system) translates human-readable domain names like www.example.com into IP addresses like 192.0.2.44 that machines use to communicate.
In AWS, Route 53 is a scalable DNS web service that integrates tightly with the cloud infrastructure. As developers, we can register domains, manage DNS records, and route user requests with logic tailored to our applications. Let’s understand what this means in detail.
Understanding DNS resolution
Before explaining how DNS resolution works, it’s important to understand the role of a DNS server. A DNS server responds to queries about domain names and their associated IP addresses. Different types of DNS servers are involved in the resolution process, including recursive resolvers, root name servers, top-level domain (TLD) servers, and authoritative name servers.
