Production-ready AWS multi-tier architecture spans compute, storage, networking, and security services across us-east-1 Region. Traffic flows from Route 53 through CloudFront and WAF to Application Load Balancer, distributing requests to Auto Scaling EC2 instances in public subnets and ECS Fargate containers in private subnets. Backend services include RDS Aurora with ElastiCache caching, DynamoDB for NoSQL workloads, Lambda for event processing via SQS and SNS, and S3 for object storage. Security layers integrate IAM, Secrets Manager, KMS for encryption, Cognito for authentication, and CloudWatch with CloudTrail for observability.
