Domain Registrar vs. DNS Service: Understanding the Difference

When setting up a domain for your website or application, it's crucial to differentiate between a domain registrar and a DNS (Domain Name System) service. Both play essential roles in the domain management process, but they serve different functions. Here's a simplified breakdown of the concepts discussed in the lecture:

Domain Registrar

• A domain registrar is where you purchase your domain name (e.g., example.com).
• You typically pay annual fees to maintain ownership of the domain.
• Examples include Amazon Registrar, GoDaddy, and Google Domains.

DNS Service

• A DNS service allows you to manage your DNS records, which are crucial for directing traffic to your website.
• Most domain registrars offer DNS services, allowing you to manage your domain's DNS records through their platform.
• AWS Route 53 is an example of a DNS service that can be used regardless of where you purchased your domain.

Summary

• A domain registrar is used for purchasing and renewing your domain name.
• A DNS service manages DNS records that control where your domain's traffic is directed.
• You can mix and match services: purchase a domain from one provider and use another for DNS management by updating NS records.
• This flexibility allows you to choose the best services based on your needs, pricing, and features.

Key Takeaway

Understanding the distinction between domain registrars and DNS services is crucial for effectively managing your domain's online presence. By leveraging the strengths of different providers, you can optimize your setup for reliability, cost-efficiency, and performance.
