In one sentence
Route 53 selects destinations through DNS, CloudFront caches content at the edge, and Global Accelerator optimizes global network paths.
Key points
- Route 53 routing policies and health checks influence which endpoint a name resolves to.
- CloudFront is a CDN for HTTP content, edge caching, TLS, WAF, and private origins.
- Global Accelerator provides static anycast IPs and accelerates TCP/UDP traffic without caching.
Exam takeaway
These services can be combined because they solve DNS, content delivery, and network-path problems at different layers.
