Multi-AZ video streaming platform leveraging CloudFront CDN, WAF, and Route 53 for global content delivery and DDoS protection. Traffic flows from users through CloudFront to a WAF-protected Internet Gateway, then to Application Load Balancers distributing requests across Auto Scaling EC2 t3.large instances in two availability zones. Application servers cache frequently accessed data in ElastiCache clusters and query DynamoDB metadata tables replicated across AZs for fault tolerance. CloudWatch monitors all compute and application metrics, while S3 stores video content and Cognito handles user authentication. This architecture demonstrates best practices for low-latency streaming, automatic failover, and cost-optimized scaling. Fork this diagram on Diagrams.so to customize subnets, instance types, or add additional services like MediaConvert or Kinesis. The design prioritizes availability and performance by isolating application, cache, and data tiers across private subnets with NAT Gateway egress.
