Route 53 and DNS Basics
Explore the fundamentals of DNS and AWS Route 53 to understand domain resolution in cloud applications. Learn how to manage hosted zones and DNS records to route traffic effectively for public and private AWS resources, enabling you to build resilient and scalable applications.
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.
