AWS VPC Edge Routing Guide Part 4: DNS Decisions and Route 53 — Hosted Zones, the Six Routing Policies, Alias vs CNAME, and Health Checks
The decision that always comes before the entry points in Parts 1, 2, and 3 — DNS. Route 53's Public vs Private Hosted Zones, the decisive difference between A / CNAME / Alias records, the six Routing Policies (Simple / Weighted / Latency / Geolocation / Geoproximity / Multi-value / Failover), the three kinds of Health Check, and the decision boundary among Route 53, Global Accelerator, and CloudFront. The DNS layer in the series; the synthesis closes in Part 5.
