What is Amazon Route 53?
Amazon Route 53 is a highly available and scalable Domain Name System (DNS) web service from AWS that combines three central functions: domain registration, DNS routing, and health monitoring. The name Route 53 refers to the traditional DNS port (TCP/UDP port 53) and signals the core function of the service: routing user requests to infrastructure.
Unlike many traditional DNS providers, Route 53 offers deep integration with AWS services and intelligent routing policies that go beyond simple DNS. The service uses a global anycast network across numerous edge locations worldwide and offers a tiered service level agreement with service credits when availability thresholds are not met.
Route 53 is well suited for DNS hosting for websites and applications, traffic management with complex routing policies, disaster recovery through automatic failover, global load balancing based on user location or latency, and domain registration and management for numerous top-level domains.
Core Features
- DNS Hosting: Highly available DNS for websites and applications
- Domain Registration: Register and manage numerous top-level domains
- Routing Policies: Seven different routing options for traffic management
- Health Checks: Monitor endpoint availability from global locations
- Resolver: Hybrid DNS for VPCs and on-premises networks
Typical Use Cases
DNS Hosting for Web Applications
Host DNS for your domains with global availability and low latency. Route 53 Alias records enable seamless integration with AWS resources like ELB, CloudFront, and S3 without additional DNS lookups. Queries to AWS resources via Alias records are free.
Traffic Management and Load Balancing
Distribute traffic across multiple endpoints using weighted, latency based, or geolocation routing. Route 53 automatically routes users to the closest or fastest endpoint. Health checks ensure traffic only goes to healthy resources.
Disaster Recovery with Failover
Configure automatic failover between primary and backup resources. Route 53 continuously monitors your endpoints and automatically redirects traffic when failures are detected. Application Recovery Controller supports fast, controlled failover for multi region applications.

Frequently Asked Questions
What is Amazon Route 53?
Amazon Route 53 is a highly available and scalable Domain Name System (DNS) web service from AWS. Route 53 reliably connects user requests to infrastructure on AWS or outside. It offers three main functions: domain registration, DNS routing, and health checks.
Which routing policies does Route 53 support?
Route 53 offers seven routing policies: Simple (standard DNS without intelligence), Weighted (traffic distribution by percentages), Latency based (routes to the region with lowest latency for the user), Failover (primary/secondary with health checks), Geolocation (based on the user's geographic origin), Geoproximity (based on geographic proximity with bias factors), and Multivalue Answer (returns multiple random healthy endpoints).
How do health checks work in Route 53?
Route 53 Health Checks monitor availability and performance of your endpoints from numerous global locations. They can monitor HTTP, HTTPS, and TCP endpoints, validate status codes, measure response times, and perform string matching on response bodies. Upon failures, Route 53 can automatically fail over to backup endpoints. Health checks can also monitor CloudWatch alarms (calculated health checks).
What is Route 53 Resolver?
Route 53 Resolver enables DNS resolution between AWS VPCs and on-premises networks. Inbound endpoints let on-premises DNS servers resolve AWS-internal domains, while outbound endpoints let AWS resources resolve on-premises domains. It is ideal for hybrid cloud scenarios with Active Directory, private DNS zones, or centralized DNS management.
Can Route 53 be used as a domain registrar?
Yes, Route 53 is a full-featured domain registrar for numerous top-level domains (TLDs), including generic TLDs (.com, .net, .org), geographic TLDs (.de, .co.uk, .fr), and newer gTLDs. Domain transfers from other registrars are supported, along with automatic renewal, domain locking, and DNSSEC support. Prices vary by TLD and are listed on the official pricing page.
What does the Route 53 SLA guarantee?
Route 53 does not guarantee a flat 100 percent availability. Instead it offers a tiered service level agreement: if a hosted zone's monthly availability falls below certain thresholds (currently including 99.99%), customers receive proportional service credits against future Route 53 charges. See the official AWS SLA page for details and current thresholds.
