Understanding Domain Registrars vs. DNS Services in AWS Route 53

In this lesson, we explored the difference between a domain registrar and a DNS service and how to configure AWS Route 53 as a DNS provider, even when using a third-party registrar like GoDaddy or Google Domains.

1. Domain Registrar vs. DNS Service

What is a Domain Registrar?

• A domain registrar is where you purchase a domain name (e.g., example.com).
• Popular domain registrars include:
  • Amazon Registrar (via Route 53)
  • GoDaddy
  • Google Domains
  • Namecheap
• Domains require annual renewal fees to maintain ownership.

What is a DNS Service?

• A DNS service is responsible for managing DNS records (A, CNAME, MX, etc.).
• It determines where traffic is directed when users access your domain.
• Examples of DNS service providers:
  • Amazon Route 53
  • Cloudflare
  • Google Cloud DNS
  • GoDaddy DNS (provided with domain registration)

💡 Key Difference:

• You can buy a domain from any registrar but still use a different DNS provider (e.g., using GoDaddy for domain registration but Route 53 for DNS management).

2. Using Route 53 as a DNS Service with a Third-Party Registrar

If you purchase a domain from GoDaddy (or another provider), you can still use Route 53 to manage DNS records.

Steps to Configure Route 53 as the DNS Service

Step 1: Register a Domain (Optional)

• If using Amazon Route 53, you can purchase a domain via the Route 53 Console.
