Study Notes
AWS Route 53 Overview
- AWS Route 53 is a highly available and scalable Domain Name System (DNS) web service.
- It routes users to applications cost-effectively and reliably.
Key Features
- Domain Registration: Register and manage domain names within AWS.
- DNS Routing: Route traffic using various policies.
- Health Checking and Monitoring: Automatically monitors resources and routes traffic accordingly.
- Scalability and Reliability: Handles high traffic with a 100% availability SLA.
- Integration with AWS Services: Seamlessly integrates with other services like EC2, S3, and CloudFront.
DNS Basics
- DNS (Domain Name System): Translates human-readable domain names (like example.com) into IP addresses (like 192.0.2.1).
-
DNS Records:
- A Record: Maps a domain to an IPv4 address.
- AAAA Record: Maps a domain to an IPv6 address.
- CNAME Record: Maps a domain to another domain name.
- MX Record: Specifies mail servers for email delivery.
- TXT Record: Stores text-based information for verification.
Route 53 Components
-
Hosted Zones: Contain DNS records for a specific domain.
- Public Hosted Zone: Accessible over the internet.
- Private Hosted Zone: Accessible within an Amazon VPC.
Routing Policies
- Simple Routing: Maps a domain to a single resource.
- Weighted Routing: Distributes traffic across multiple resources based on weights.
- Latency-based Routing: Routes users to the lowest-latency resource.
- Failover Routing: Routes traffic to a healthy resource if one fails.
- Geolocation Routing: Routes traffic based on user location.
- Geoproximity Routing: Routes based on geographic proximity with optional bias.
- Multivalue Answer Routing: Returns multiple IP addresses for DNS queries.
Health Checks and Monitoring
- Continuously checks resource health.
- Supports HTTP, HTTPS, and TCP endpoints.
- Automatically redirects traffic to healthy resources if a failure occurs.
- Integrates with CloudWatch for health check logs.
Integration with AWS Services
- Amazon EC2: Maps domain names to EC2 instances.
- Amazon S3: Hosts static websites and routes traffic to S3 buckets.
- AWS CloudFront: Integrates with CloudFront for content delivery.
- AWS Elastic Load Balancing (ELB): Routes traffic to load balancers.
Security and Compliance
- DNSSEC Support: Protects against DNS spoofing attacks.
- IAM Policies: Control access to Route 53 resources.
- Compliance Certifications: Meets various regulatory requirements.
Pricing Overview
- Domain Registration: Pricing based on TLD (Top Level Domain).
- Hosted Zones: Charges per hosted zone per month.
- Queries: Billed per million queries.
- Health Checks: Charges based on the number of checks.
Use Cases
- Website Hosting: Manages DNS for web applications.
- Global Traffic Management: Optimizes routing for global users.
- Disaster Recovery: Implements failover routing for high availability.
- Hybrid Cloud DNS: Integrates on-premises and AWS resources.
