description Amazon CloudFront DNS Overview
This service is less about pure DNS resolution and more about leveraging the CloudFront CDN's edge network for DNS-related performance boosts. It is best utilized when your entire architecture is already built on AWS and requires DNS resolution to benefit from edge caching mechanisms, making it highly specialized for AWS-centric deployments.
help Amazon CloudFront DNS FAQ
Is Amazon CloudFront DNS the same service as Amazon Route 53?
No, CloudFront is Amazon's content delivery network, while Route 53 is AWS's dedicated DNS service. A production AWS architecture may use Route 53 for DNS and CloudFront for cached delivery, but they solve different problems.
What does CloudFront add to a website?
CloudFront serves cached files from edge locations closer to users, which can reduce latency for static and media content. It is most useful when the application is already designed around AWS origins such as S3 or an application load balancer.
Can CloudFront replace a domain registrar?
No, CloudFront does not register domains. You still need a registrar and DNS configuration, commonly using Route 53 or another DNS provider, to point a domain toward the CloudFront distribution.
When should I use Route 53 instead of describing CloudFront as DNS?
Use Route 53 when you need authoritative DNS records, health checks, routing policies, or domain registration within AWS. Use CloudFront when the main requirement is edge caching and delivery of web content.
