In this lesson, we explore AWS Route 53, a fully managed domain name service (DNS) provided by AWS.

​
What Is Route 53?

AWS Route 53 is a robust and scalable DNS service that facilitates several critical functions:
  • It acts as a domain registrar, allowing you to purchase domain names much like popular services such as GoDaddy and Namecheap. For example, you can register a domain like KodeKloud.com directly through Route 53.
  • It manages all DNS records for your domains, so once you register a domain, you can easily configure its DNS settings within Route 53.
  • Being a global service, Route 53 is not limited to a single region, ensuring worldwide accessibility.

​
Hosted Zones

A fundamental concept in Route 53 is the hosted zone. A hosted zone is a container for all the DNS records associated with a specific domain (e.g., KodeKloud.com). When you create a hosted zone:
  • AWS reserves four dedicated name servers for that domain.
  • For any additional domain, such as fastcars.com, AWS allocates another distinct set of four name servers to manage its DNS records and rules.
The image illustrates the concept of hosted zones in Amazon Route 53, showing how DNS records are organized and allocated four nameservers by AWS for different domains.
  • AWS Route 53 functions as both a DNS service and a domain registrar.
  • It delivers global coverage and is not confined to any specific region.
  • Hosted zones provide a structured environment where each domain receives four dedicated name servers for optimal DNS management.

​
Summary

  • AWS Route 53 is a fully managed DNS service and domain registrar.
  • It operates at a global level.
  • Hosted zones are collections of DNS records for specific domains, with each hosted zone having four dedicated name servers reserved by AWS.
In the next section, we will provide a demonstration to illustrate how to set up and manage hosted zones effectively.
