Amazon Route 53 is AWS's highly available and scalable Domain Name System (DNS) web service. It provides several key functions: 1. Domain Registration: Allows you to register domain names for your applications. 2. DNS Routing: Translates user-friendly domain names like www.example.com into IP addresses like 192.0.2.1. 3. Health Checking: Monitors resources and routes traffic away from unhealthy endpoints. 4. Traffic Flow: Provides global traffic management to improve latency and reliability. Route 53 offers various routing policies: - Simple routing: Directs traffic to a single resource - Weighted routing: Distributes traffic across resources based on assigned weights - Latency-based routing: Routes traffic to the region with lowest latency - Geolocation routing: Routes based on user location - Geo-proximity routing: Routes based on resource location and optional bias values - Failover routing: Routes to primary resource unless it's unavailable - Multivalue answer routing: Returns multiple IP addresses for DNS queries Route 53 integrates seamlessly with other AWS services, making it easy to connect user requests to infrastructure running on AWS—like EC2 instances, ELB load balancers, or S3 buckets. It's designed for 100% availability through global distribution of DNS servers, automated DNS health checks, and features like private DNS for Amazon VPC. Route 53 Resolver provides recursive DNS capabilities for your VPCs and on-premises networks, enabling hybrid DNS resolution across environments. Pricing is based on hosted zones, queries, health checks, and domain registrations, with no long-term commitments required.
