3Edge and DNS Design
- 3.1Route 53 and Routing Policies
Route smartly with DNS—understand Route 53, latency/geolocation/weighted/failover routing, health checks, and alias records. Pick the policy that fits the goal.
- 3.2Content Delivery with CloudFront
Fast and secure at the edge—understand CloudFront, caching, origins (S3/ALB), origin protection with OAC, and TLS/WAF at the edge. Deliver with low latency from edges worldwide.
- 3.3Global Accelerator and Choosing Edge Services
The other edge—understand Global Accelerator, static anycast IPs, the AWS backbone, fast regional failover, and how it differs from CloudFront. Choose it for non-HTTP or static-IP needs.
