Overview

Implement DNS management strategies for traffic routing, failover, geo-routing, and high availability using Route53, Azure DNS, or CloudFlare.

When to Use

Domain management and routing
Failover and disaster recovery
Geographic load balancing
Multi-region deployments
DNS-based traffic management
CDN integration
Health check routing
Zero-downtime migrations

Quick Start

Minimal working example:

# route53-setup.yaml
apiVersion: v1
kind: ConfigMap
metadata:
  name: route53-config
  namespace: operations
data:
  setup-dns.sh: |
    #!/bin/bash
    set -euo pipefail

    DOMAIN="myapp.com"
    HOSTED_ZONE_ID="Z1234567890ABC"
    PRIMARY_ENDPOINT="myapp-primary.example.com"
    SECONDARY_ENDPOINT="myapp-secondary.example.com"

    echo "Setting up Route53 DNS for $DOMAIN"

    # Create health check for primary
    PRIMARY_HEALTH=$(aws route53 create-health-check \
      --health-check-config '{
        "Type": "HTTPS",
        "ResourcePath": "/health",
        "FullyQualifiedDomainName": "'${PRIMARY_ENDPOINT}'",
        "Port": 443,
// ... (see reference guides for full implementation)

Best Practices

✅ DO

Use health checks with failover
Set appropriate TTL values
Implement geolocation routing
Use weighted routing for canary
Monitor DNS resolution
Document DNS changes
Test failover procedures
Use DNS DNSSEC

❌ DON'T

Use TTL of 0
Point to single endpoint
Forget health checks
Mix DNS and application failover
Change DNS during incidents
Ignore DNS propagation time
Use generic names
Skip DNS monitoring
