Amazon Route 53
A highly available Domain Name System service that routes users to internet applications by translating names into endpoint addresses and applying routing policies.
Key points
- Route 53 supports domain registration, DNS resolution, health checks, and routing policies.
- DNS routing can direct users to healthy or geographically appropriate endpoints.
- Route 53 does not cache and deliver application content.
Best-known use cases
- Host DNS records for an application domain.
- Route clients to healthy endpoints using DNS policies.
What candidates often confuse it with
- Route 53 is DNS; CloudFront caches and delivers content at edge locations.
- Global Accelerator improves network-path performance for supported applications but is not authoritative DNS hosting.
Key Cloud Practitioner takeaway
Domain names and DNS routing point to Route 53.
