About This Architecture
AWS Tokyo single-AZ web app with CloudFront CDN delivers a resilient three-tier architecture spanning ap-northeast-1a and ap-northeast-1c availability zones. Users route through Route 53 DNS to a WAF-protected CloudFront distribution, which caches video content from S3 while routing dynamic requests through an Application Load Balancer to EC2 t3.small instances and RDS MySQL databases. CloudWatch monitors CPU, memory, and disk metrics, triggering CloudWatch Alarms that send SNS notifications via email when thresholds breach.
